  • did some of your plugin or theme require php 8.1? If not, try change to php 7.4

    7.4 is unsupported so I’m hesitant to go that route due to potential security vulnerabilities.

    This problem may be a plugin or theme conflict. Please attempt to deactivate all plugins and switch to the default Twenty Twenty-Two theme. If the problem goes away, re-activate them one by one to identify the source of the problem.

    If you can install plugins, install Health Check. On the troubleshooting tab, you can click the button to deactivate all plugins and change the theme for you while you’re still logged in without affecting normal visitors to your site.
