I've seen similar problems to mine but not identical, so I thought I'd throw this out there to see if anybody can help me.
I'm moving my blog to a new host (same domain name and same folder on the domain, though). I uploaded WordPress 2.5, installed the database and can login to the Dashboard. However, when I point my browser to the blog's location, all I get is a blank page. I've rebooted the computer, cleared the cache and still get a blank page. I tried posting and it seems to go through.
I'm really stumped as to what to try next. Last time I checked (about a week ago), the blog worked fine on the old host and there were no troubles with posting either.
Can anybody suggest what could be the problem?
