    Hello,

    I have a broken WordPress. The website itself looks normal, but the admin center is quite stuck, some pages won’t even load (e.g. when searching for plugins it freezes and I have to refresh the page). And when using some plugins it shows errors (e.g. WP Fastest Cache reports an unknown error or WPvivid Backup reports SyntaxError: Unexpected token ”, “”… is not valid JSON

    Obviously there is an error directly in WordPress, but I have no idea how to fix it.

    Please help

    Thank you

    Hello,

    I checked have your website and it looks like you have put the website under maintenance mode. As the website is still visible, this may not be a WordPress core error directly.

    From the problems you mentioned, the issue may be related to a plugin conflict or a hosting-side error which is causing invalid JSON responses in wp-admin.

    If you are still able to access your admin dashboard, I would recommend temporarily disabling all the plugins for testing. Make sure that you do not uninstall them directly. Just deactivate them and check whether the admin area starts working normally again.

    If disabling the plugins fixes the issue, then reactivate them one by one so that you can identify which plugin is causing the problem.

    If the issue still continues even after this, I would suggest you contacting your hosting provider and asking them to check for PHP errors, ModSecurity blocks, or REST API/AJAX failures.

    This might help you.

    Thank you.

    I would recommend the following steps:

    • Go to Settings > Permalinks and save the settings again without making any changes. This will reset WordPress’s internal URL cache.
    • As a test, deactivate all plugins. This will rule them out as the cause.
    • If it still doesn’t work properly, switch the theme to a default theme like TwentyTwentyFive. At that point – with no plugins and a default theme – there should be no issues.
    • Also check under Tools > Site Health to see if there are any messages there.
