Server error status: Internal Server Error [500]

Hello, I'm trying to install your plugin Popup but I get a red error message on top of header with
Server error status: Internal Server Error [500]

Could you help me to understand what's the problem?

    Hi Pietro,

    Do you have a custom menueditor or some security plugin installed?

    With support access I can't see or access your plugins pages or the WPMUDEV Dashboard plugin.

    Your admin seems to be locked down.

    Does it install if you try to install it via the project page? rather than the dashboard?

    Though a red notice, usually implies something on the server blocking it. More often than not it is related to Curl not functioning properly, or an incorrect version of openSSL.

    I also notice you are using an extremely old version of Wordpress, I would recommend updating to the latest, as this could also have an impact in usability of some plugins.

    Can you check your server Error logs to see if anything is listed.
