Greetings - I am hoping that this is a simple issue which I have simply overlooked, and you'll easily be able to help remedy.
Multisite on 3.1.4 - 8 subsites set up as subdomain
I have tried every type of upgrade there is - automatic, manual - short instructions, manual - long instructions, etc.
I have backed the live site up and set it up locally. I have deactivated all plugins.
I get a white screen on front end and backend *every time*.
I've tried about 6 times. I am close to simply starting with a whole new install and building the network from scratch, importing all content through XML files, and seeing if that works.
Thoughts? Any insight greatly appreciated.
