Until yesterday I had a pretty successful blog. All of a sudden the firewall of my hosting provider banned me as an attacker. I couldn't edit or post my own blog. I couldn't even visit it.
According to my provider it had to be something in the theme I was using. This wasn't very logical to me as I didn't change anything in the theme the last couple of month. But the log files indeed said something about the theme.
Afer 20 or so e-mails and having the same problems in other locations I decided to change the theme. Because I just could enter my domain via ftp or CPanel because I got immediately banned when I visited it directly, I deleted the theme (made a backup of course) and the tried to go to the wp-admin area to select a new theme.
All I got when I arrived at my page was a blank, white page and there wasn't a login area to see when I typed in wp-admin.
In the end I managed to make a backup of my database. Then I upgraded my blog manually to WP 3.0 but the result kept the same. A white page and nowhere a login area to find.
Last but not least I thought to be clever by creating a new directory and then manually making a fresh installation of WP 3.0 from scratch. Once it worked I would then delete the old folder and rename the new one, so that all the incoming links wouldn't be broken.
But nothing works. the only thing I get is a blank page and no area to login. If you ever asked yourself why people become chain smokers or alcoholics. This is why.
Going to have a cigarette and wondering if there is anybody out there with a comparable experience.
Thanks for letting me know.
