Hi
I’ve got the exact same problem.
Tried to do something and then got the same database errors.
I’ve done the repair script and said all tables ok so I removed the extra line and restarted. No dice, it went back to the initial page where I needed to add the same line of code to repair the db.
Tried to run the installation again, as mentioned in this post, but that only gets me back to the error page, and the page which tells me to put the repair code in the php file.
Can anyone help?
