I've upgraded my forums database to MySQL. All appears to work, except when a new user signs up and then tries to login he/she is met with a 500 - Internal Server Error.

Username: thedeputydog
Password: freedom

I have web.conf set to:
<customErrors mode="On" />

TIA

firstly you should turn customErrors to Off, then try adding

<system.webServer>
<httpErrors errorMode="Detailed" />
</system.webServer>

to your web.config

Thanks for help HuwR.
I solved the problem. I forgot to put a username in the username box when signing up. I added a username and bingo - it worked! Dummy me.
All is working again.
