Lots wrong

Stacy-
Thank you for reaching out. First off, very sorry for the delay – I did not receive a notification of your post :/

In our extensive tests, 95% of the issues have been attributed to caching. That said, please try clearing your browser’s cache. If that does not help the issue, please try clearing the cache via your WP site’s caching plugin (if you have one activated).

If this does not work, it could be an issue with multisite compatibility. We’ve had users report that they are able to use the plugin on multisite, but other users have had conflicts (depending on the configuration).

open wp-admin/plugin-editor.php show this：

Thanks for your comment, @czweb.
Can you email direct through our PRO support page so we can figure out what is causing the conflict? This is not an error we’ve seen before, and I’d like to learn more about your configuration in order to solve it.

Thanks.
