@tomatobob1138 I’m not the plugin author, however I have tested this plugin on all versions of PHP 8.0 and up and have not had any issues like what you are describing.
If you go in your WordPress dashboard, click on “Tools” and “Site health” and then click “Info” and finally, “Server” – do you show the correct PHP version there? In some cases, the web host could be on 8.0 and up, but sometimes the WordPress folder might not be running that version. Some web hosts will have the PHP version defined in the site’s “.htaccess” file.
If site health shows the older version of PHP, such as 7.4, then that would be why you are getting the notice. In that case, you may wish to just contact your hosting provider to get them to set the PHP version for you, unless you have options in the control panel of your hosting to set this easily.
If you verify that you are indeed on PHP 8.2 from within the Site Health screen, then hopefully the plugin author will be able to help you. It might help to identify the conflict if you have a server error log (maybe post it on pastebin and put the link here).
