 * Hello Michael,
 * I did some extensive testing of the site and it appears that the 502 error that
   you are experiencing in the wp-admin screen is being generated by the NextGen
   Gallery plugin. Once I disabled that plugin, the 502 errors stopped immediately.
   You will want to contact the developer support team for the NextGen Gallery for
   support assistance with that specific plugin. Currently the plugin is deactivated
   to allow for access to the wp-admin dashboard.

 * I’m not the plugin developer but was wondering what version of WordPress and 
   NextGen Gallery are you running with this error?

 * [@sagemediallc](https://wordpress.org/support/users/sagemediallc/) – Aside from
   [@girdy74](https://wordpress.org/support/users/girdy74/) (thanks!) questions,
   there would still be more that we may need to know you have looked into.
 * Have you tried deactivating all of your plugins, clearing your browser cache (
   and site caches if you are using a caching plugin), then reactivating the NextGEN
   plugin?
 * If this fixes the problem then it was likely one of the deactivated plugins that
   was causing an issue. Now, retrace your steps activating each plugin and re-checking
   to see if the problem returns. If it does then that last activated plugin was
   probably the one. Keep reactivating and in most cases it is also best to keep
   checking after each plugin, sometimes there may be more than one plugin on a 
   site that will create an issue. If you do find one (or more) plugins causing 
   this problem we would greatly appreciate your feedback on them so the developers
   may address them as soon as they can.
 * Also to note, in rare cases it may be the theme itself that is causing a conflict
   so while you have just the NextGEN plugin activated you might consider temporarily
   switching to one of the default WordPress Twenty series themes and see if this
   corrects the issue as well.
 * If the problem still persists after all of this we would still want to know, 
   even more so, as we will still want to sort out the issue and may need additional
   details.
 * Thanks!
