I was tweaking settings last night in the admin area when I got a WSOD and had to SSH to my server and rename the plugins folder. This fixed everything and I began setup again today. I singled out the plugin that once I network enable "Domain Mapping" the site goes down. I tried deleting the two domain mapping tables I found from my database incase there was a bad setting there but then enabling Domain Mapping again broke the site. I had to rename the plugin to get my admin area back again. Please help, this is a crucial plugin for my setup.
