I got the White Screen of Death (WSOD) today.
I got advice from my hosting company which didn't fix anything (getting rid of plugins, themes and .htaccess file) until I reset the permalinks.
I reinstalled my plugins one by one in a new plugins folder.
Most worked - except Appointments+ took me to WSOD again.
Now I tried to update permalinks and that gives me the WSOD.
...and the widgets I took from inactive and reinstalled where they were - do NOT appear if they are a WPMU plugin widget - unless they are on a buddypress page.
An external plugin works - just not the WPMU ones.
Can someone assist please?
