Please attempt to disable all plugins, and switch to the default Twenty Twenty-One theme. If the problem goes away, enable 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 disable all plugins and change the theme for you, while you’re still logged in, without affecting normal visitors to your site.
Thank you for the recommendation. I installed Health Check and it seems the issue is my current theme. It hasn’t been updated by the creators in a while and now that the version of WordPress has just updated, it seems to be causing problems. So now I guess my site is getting a complete theme overhaul for the new year. Thanks for the guidance!
