Provided that this is true, play out a hard-invigorate on your program (CTRL + F5 on Windows frameworks and CMD + CTRL + R on OS X frameworks).

Rename plugins.old back to modules and login to your WordPress administrator dashboard. It’s an ideal opportunity to locate the tricky module.

Actuate the modules individually while reloading your site after every initiation. Rehash this until you pinpoint the module that is raising a ruckus. The hazardous module will clearly reproduce the 502 terrible passage mistake on enactment, which may keep you out of the administrator zone.
