I've been running WPMU for 3+ mo and haven't made any changes to it. I've updated a couple themes recently, but that's it. Now all of my wpmu site and main site are displaying nothing but a blank page. No source, nothing at all.
Any idea why this is happening and how to troubleshoot it? I removed all of the plugins and it still does it.
Look in your error logs and tell us what you see
It's not throwing any errors. I entered a sub domain that didn't exist to see if that did anything, and it did add a couple lines to the error log. So I know logging is working (at least some.)
"I've updated a couple themes recently, but that's it."
Did you do anything like, change theme folder names?
White screen = error. Reading error logs tells us what it is.
Blah, sorry for wasting your time. I totally spaced that over the weekend I was going to update a bunch of themes that I have new versions of. So I removed the old ones but got sidetracked and didn't upload the new ones.
Total basic mistake. I had other stuff come up I had to deal with and totally forgot I was working on it.
On a side note, should such an issue be resulting in an error in the log?
Thanks
It does seem a bit drastic that a missing theme can do something so terminal.
If the missing themes was set as the active theme, then yes. It terminates itself. :)
