Try disabling all your active plugins on Safari. It’s a drastic yet effective way to pinpoint whatever is stopping your browser from displaying web content properly:

  1. Open your Safari browser and click on Safari at the top.

  2. Then, select Preferences.

  3. Go to the Websites menu option.

  5. Click on Done once you are finished.

Next, if you want to remove all the plugins from the system. Simply visit /Library/Internet Plug-Ins/ to access the files. Then, you can drag all the plugins to the trash and it will be deleted permanently.

To identify if the issue is isolated to any particular plugin, try adding them individually and check if it is resolved.

2. Try Another Browser

Since users are primarily seeing this error on Safari, you can try using a different browser, such as Opera One. See if the issue persists. While it doesn’t actually solve the problem at hand, it’s a quick, easy solution if you need to access something only urgently.

3. Update Plugins

An outdated plugin could also cause these errors. Updating your plugins to their latest versions might resolve the incompatibility issues that are blocking specific web content. Make sure you visit the official websites of your extensions, of course.

4. Update Your Browser

Lastly, you can also update your Safari browser. If this is a known issue on older Safari versions, Apple might have already resolved it in its more recent releases. Whatever the case, using the latest version improves security, performance, and compatibility with web content, including plugins.

  1. Go to the Apple menu and open System Preferences.
  2. Click on Software Update.
