When I try to update a plugin from the WPMU DEV > Plugins page I get this error:
“Failed: Unexpected response from WordPress.”
I am also getting this after trying to run the updates, the site literally goes into maintenance mode and crashes (then the server stops loading and the plugins don’t update):
“Maintenance Briefly unavailable for scheduled maintenance. Check back in a minute.”
The issue is specific to your guys plugins, the rest are working perfectly. This problem is occurring on all my sites, they are all hosted on the same server.
