WPMU Dashboard causing 502 errors


I am using WPMU Dashboard on several of my sites with no issues. However, when I activate it on one specific site http://www.sensites.com I instantly get 502 errors across my entire network of sites.

I then have to deactivate the plugin manually though my hosting provider because I am unable to access anything else.

Without the dashboard plugin activate I am unable to update my WPMU plugins.

Have you experienced this issue before?

    Hello Christopher,

    I hope you are well today.

    When you are able to run a plugin successfully on multiple sites, but unable to run it on one specific site without getting a 502 error, all on the same server, this is almost always a case of a plugin conflict.

    The best thing to do is to run a plugin conflict test.

    * Place your sites in Maintenance Mode by installing and activating WP Maintenance Mode. You will need to go into the Admin -> Settings -> WP Maintenance Mode of each network site and set the plugin as active.
    * Then, deactivate all other plugins and try installing WPMU DEV Dashboard on your Network Admin Site.
    * If the DEV Dashboard then installs successfully, activate each plugin one at a time until you are able to reproduce the 502 error. The last plugin you activate prior to the error will be the plugin that has the conflict.

    You can learn more about performing a plugin conflict test here -> https://premium.wpmudev.org/manuals/using-wpmu-dev/getting-support/

    Let us know if this leads to a solution for you. If not, we will be happy to dig into this issue further for you! :slight_smile:
