Site Displaying Errors To Visitors

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.

It’s not a plugin or lupus. Put debug-bar back in place and/or find out where it’s being called for something and remove that. Whether to show errors or not is a PHP setting, ask your host. I can help with this for a reasonable fee.

I would recommend activating the debug mode mentioned in the error message: https://www.ads-software.com/documentation/article/debugging-in-wordpress/ – this would show you in a log file what is actually causing the error message.
