I'm upgrading my blog from 2.2.3 to 2.3. I get to the message: Your database is out-of-date and click on the Upgrade your database link and wait patiently for a long time... and then I get this:
The specified CGI application exceeded the allowed time for processing. The server has deleted the process.
Since then I'm not able to access my database at all. I get "Error establishing a database connection" on all my blogs connected to that database (they have different prefixes), not just the one that I tried to upgrade
I have no idea what causes it or how to proceed from here.
Advice will be highly appreciated.
