There’s nothing in PHP 8 or 6.2.2 that we are aware of which would prevent the plugin from working properly. We also run this plugin on several PHP 8 + 6.2.2 websites and have not run into any issues.
This leads up to believe that it may be a plugin or theme conflict. We would recommend taking a backup of your website, understanding how to restore your back up, and installing the?WordPress Health Check & Troubleshooting Plugin. This will allow you to safely disable plugins and revert to a default theme ( just for your admin user so that this does not affect visitors ). You can then enable each plugin one by one until you find the culprit. For more information, we do recommend reading?their documentation.
An alternative option is to edit your topic and add a link to your website in which we can take a look at the dev tools to see if there are any JavaScript errors causing an issue and check the source to ensure everything is loading as expected. Please note that if you link your website outside the provided topic link box, this link will be publically available (and usually not an optimal solution for most users).
Hopefully using the above resources you’re able to resolve your issue but should you have any questions or can provide further information we can assist further. Have a wonderful rest of your week!
