    Thanks for the report but Query Monitor doesn’t affect the loading of other plugins. It sounds like there’s an issue with the object cache on your site (often Redis or Memcached) which means after activating or deactivating plugins the value in the cache is not updated.

    Your best bet is to try clearing the object cache and contacting your web host if that doesn’t help.

    Hello John,
    thank you for your quick reply.

    Okay, but isn’t it funny, that the problem is solved immediately as soon as QM is deactivated?
    Maybe QM affects the clearing of the object cache?

    Hi John,
    the object cache was a sure-fire bet!

    Although I had deactivated QM the problem occured again later on.
    So, after activating a plugin I purged all caches (w3 total cache) and there was no problem anymore.

    Thanks a lot!
