I was having difficulties getting my login to stick, so I was checking out the definition of $baseurl in conf/_config.php (0.9.x).

After replacing the _config.php file, all of a sudden any attempt to access the site gave me an error that I'll paraphrase (lost the exact text) as: "Your version of b2evo is __. You haven't finished installing yet. Please run...."

I solved it by removing and reinstalling b2evolution and everything is working fine.

However, it was such a scary error, because it took the site completely down.

Does anyone know exactly what triggers this, so that next time (crossing my fingers it won't happen) I can solve it less drastically than re-installing?

Thanks in advance for any help!
