The strangest thing has just happened to me. I have an account with a web hosting service. Through that service I've installed Drupal, and successfully configured it. It's been running for months.
I also have Gallery installed, and the Gallery module.
Today I was doing some administration of the Gallery site. Adding pictures, deleting some bogus accounts, just basic, basic stuff.
Now when I hit my site the main URL, the site comes up fine. However, once I log in, I get back empty responses for requests. And when I say empty I mean empty, nothing, no html at all.
If I delete the cookie, that tells Drupal I'm logged in, then I can see the site fine. I can navigate, move through blogs and stories, and generally see everything. As soon as I log in, blamo.. Nothing.
And this happens with both the accounts that I have that are administration accounts.
When I created a new account, then that was great, Logins for that new account worked fine. Requests to Drupal generate content.
Can any one give me some idea of how to fix this problem???
