This Webpage was Reloaded Because a Problem Occurred

What does “This webpage was reloaded because a problem occurred” mean in Safari?

This warning appears when Safari’s WebKit engine detects that a page has crashed or become unresponsive. Instead of leaving you staring at a frozen screen, Safari automatically reloads the tab. You might also see a variation that reads “a problem repeatedly occurred,” which means the page keeps crashing every time Safari tries to reload it.

The message itself is vague on purpose. Safari doesn’t specify the exact cause, so the issue could stem from your Mac, the browser, or the website. If Safari isn't working in other ways too—freezing, refusing to open pages, or quitting unexpectedly—the root cause may be deeper than a single webpage.

Why does Safari show “This webpage was reloaded because a problem occurred?”

From our experience, several factors can trigger this Safari error. Understanding the cause helps you pick the right fix, so let’s walk through the most common ones.

1. High memory or CPU usage

Safari shares your Mac’s memory and processor with every other app running on your Mac. When a webpage loads heavy media, runs complex JavaScript, or streams video, it can consume a large chunk of those resources. Plus, if you open too many tabs on top of that, Safari may not have enough room to keep each page alive.

Older MacBook Air or MacBook Pro models with limited RAM are especially prone to this vulnetrability. You can see CPU usage in Activity Monitor to find out whether a specific page or process is hogging resources.

2. Website compatibility or page errors

Not every website is built to play nicely with Safari because of the incompatible or outdated technologies under its hood. Poorly optimized pages, broken JavaScript, or elements designed only for Chrome can cause Safari to choke. If a page works in another browser but crashes in Safari, compatibility is likely the culprit.

3. Browser extensions or content blockers

Extensions add functionality to Safari, but they also inject extra code into every webpage you visit. An outdated or buggy add-on can interfere with how a page loads—causing repeated crashes, reloading loops, or blank screens. Content blockers, while helpful for removing ads, sometimes strip out page elements that Safari needs to render the site correctly.

If you suspect an extension is behind the issue, you can uninstall extensions one at a time to isolate the problematic one.

4. Cached data or temporary browser files

Safari stores copies of websites locally so pages load faster on your next visit. Over time, these cached files can become outdated or corrupted. When that happens, Safari may try to load a broken local version of a page instead of fetching a fresh one—and the mismatch can trigger the reload warning.

5. Outdated Safari or macOS version

Apple regularly patches Safari through both macOS updates and separate software updates.  This means that Safari can receive updates independently from the broader macOS updates, which may include specific fixes for Safari or other software components. That’s why running an older macOS version means you’re also running an older Safari build—one that may contain known bugs or lack support for modern web technologies. Remember that a simple macOS update can resolve crashes tied to outdated software.

How to fix “This webpage was reloaded because a problem occurred?”

Now that you know what’s causing the issue, let’s go through the fixes. Start from the top and work your way down—most people find a solution within the first few steps. And if your Mac is running hot while Safari acts up, that’s worth investigating too—sometimes Safari causes overheating when a webpage is stuck in a crash-reload loop.

1. Close unused tabs and reduce memory usage

Every open tab uses memory, even if you’re not actively looking at it. Closing the ones you don’t need is the quickest way to free up resources and give Safari room to breathe. If your browser is Safari very slow in general, this step alone can make a noticeable difference. Learn how to do it below:

1. Look at your tab bar and identify pages you’re not using right now.
2. Close each unnecessary tab by clicking the small “x” on its left side.
3. Quit any other memory-heavy apps running in the background—video editors, design tools, or virtual machines.
4. Try reloading the page that was causing the issue.

2. Restart Safari

Restarting the browser clears out temporary processes, flushes short-term caches, and gives Safari a clean slate. It’s simple, but it resolves more issues than you’d expect—and here’s how to do:

1. Press Command + Q to quit Safari.
2. If Safari won’t quit, press Option + Command + Esc to open the Force Quit window, select Safari, and click Force Quit.
3. Wait a few seconds, then reopen Safari from the Dock or Applications folder.
4. Navigate back to the page and check if the issue persists.

3. Restart Mac

A full restart clears your Mac’s memory, stops lingering processes, and resets system-level caches. If Safari’s issue is tied to a broader system resource shortage, a reboot is often all it takes. Here’s how:

1. Save any open work across your apps.
2. Click the Apple menu in the top-left corner and choose Restart.
3. After your Mac boots up, open Safari and revisit the page.

4. Clear Safari cache and website data

Clearing stored website data removes corrupted or outdated files that may be interfering with page loading. You can clear Safari cache in just a few clicks:

1. Open Safari and click Safari in the menu bar.
2. Select Settings (or Preferences on older macOS versions).
3. Go to the Privacy tab and click Manage Website Data.
4. Click Remove All to clear the cached data, then confirm.
5. Reload the page.

5. Test the website in a private window

A private browsing session disables extensions and ignores cached data—two common causes of this error. Opening the page in incognito mode helps you figure out whether the issue lies with Safari’s stored data or add-ons. Follow our instructions:

1. In Safari, click File in the menu bar.
2. Select New Private Window (or press Shift + Command + N).
3. Paste or type the URL of the webpage that’s been crashing.
4. If the page loads without issues, the cause is likely an extension or cached data.

6. Try opening the page in another browser

This step helps you determine whether the issue is on Safari’s side or the website’s. If the page loads in Chrome, Firefox, or another browser, the problem is specific to Safari. If it crashes everywhere, the website itself is likely at fault. Here are our instructions:

1. Open a different browser—Chrome, Firefox, or Edge.
2. Navigate to the same URL.
3. If the page works, the issue is Safari-specific. Continue with the remaining fixes below.

7. Disable or test browser extensions

Turning off extensions one by one is the most reliable way to find a problematic add-on. Follow our hints below:

1. Open Safari > Settings > Extensions.
2. Uncheck every extension to disable them all at once.
3. Reload the page. If it works, re-enable extensions one at a time to find the culprit.
4. Once you’ve identified the faulty extension, remove it or check for an update from the developer.

An extra help from our team:

 

Be aware of the changes in the Step 1 in newer versions like macOS Tahoe, Apple renamed the section slightly. So instead of “Extensions”, it may appear as:

 

👉 Safari → Top-left menu bar → Safari Extensions.

 

Whereas on older versions (like macOS Sonoma or earlier), you’ll see it as:

👉 Safari →Top-left menu bar →  Settings → Extensions.

8. Check for macOS and Safari updates

Apple bundles Safari updates with macOS releases, so keeping your system current also keeps your browser current. You can also update Safari browser independently through the App Store in some cases. Below, here’s how:

1. Click the Apple menu and select System Settings (or System Preferences on older macOS).
2. Go to General > Software Update.
3. If an update is available, click Install Now and follow the on-screen instructions.
4. After the update finishes, restart your Mac and test Safari.

9. Monitor system resource usage

Activity Monitor—built right into macOS—lets you see what is running on your Mac and how much memory or CPU each process consumes. Just follow our steps:

1. Open Finder > Applications > Utilities > Activity Monitor.
2. Click the Memory tab to sort processes by RAM usage.
3. Look for Safari or specific webpage processes consuming large amounts of memory.
4. Select a resource-heavy process and click the “x” button in the toolbar to stop it.

When the problem is caused by the website?

Sometimes the issue isn’t your Mac or Safari at all—it’s the website. Pages loaded with heavy JavaScript, auto-playing video, or broken code can overwhelm Safari’s rendering engine. If you’ve tried every fix above and the page still crashes, the site’s code is likely to blame.

A few telltale signs that the website is the problem:

• The page crashes in Safari but also behaves oddly in other browsers.
• Other users report similar loading issues with the same site.
• The page works on some visits but fails on others, suggesting the site’s server is unstable.

In these cases, there isn’t much you can do on your end. Try visiting the site later, or reach out to its support team to let them know about the issue.

How to prevent Safari “This webpage was reloaded because a problem occurred” in the future?

You can’t eliminate every webpage crash, but here are a few habits that will make them far less frequent:

• Keep macOS and Safari updated. Apple patches known Safari bugs through system updates, so don’t skip them.
• Limit the number of open tabs. Aim to keep it under 10–15 at a time, especially on older Macs.
• Review your extensions regularly. Remove any you don’t actively use and make sure the rest are up to date.
• Clear Safari’s cache periodically. A monthly cleanup prevents corrupted files from piling up.
• Use MacKeeper’s Safe Cleanup. Our tool will help you to remove junk files, caches, and logs that accumulate across your Mac, freeing up memory and storage that Safari can use.
• Monitor system resources with Activity Monitor. As an altentaive, you can also benefit from MacKeeper’s Memory Cleaner within our app to catch resource-heavy processes before they cause a crash.
