After upgrading my 2-year old blog (one of them) to WP 2.5 succesfully I started getting an incredibly annoying problem... It's only happening in one of the blogs:
I get an Install Screen wherever I point my browser to. Like the blog was new... After retrying a couple of times the blog comes back, only to get blank again after some random time (could be 1 second, or a couple of hours). When it comes back to life, I have to update permalink setting each time or individual posts cannot be accessed...
It's a real pain... And I'm loosing much needed money! Please could someone give me a hand?
