Since I first installed CB, I haven't been able to edit or create new fields. I keep getting a 500 Error message that I know it is from my hosting provider. however, why does this happen? I haven't been able to customize my fields due to this problem?

Another problem I got was that when upgrading to RC3, I could not find the configuration file on RC2. It is located on the folder stated by the instructions, but on the fresh, never installed package, not on the actual server folder! So, how do I find it? I had to configure everything again.

Help!
