    Hi there,

    When i go to our site and reload the page after installing query monitor, i get a 500 server error.
    The logs show: Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 133664768 bytes) in Unknown on line 0

    Right now WordPress memory is set to 512, but even if i increase it to 1024, i get the same messages.

    Any ideas why this is happening?

    Thanks

    Update: So i deactivated all the plugins and tried again and it worked fine. Must be a conflict with another plugin. Will try to narrow it down.

    This sort of problem isn’t usually caused by one plugin, or a conflict, but usually by combination of factors.

    If your site performs a very large number of database queries, for example via a poorly built plugin or theme, then QM can push your server over the memory limit when it tries to log and display them all.
