My site often crashes and goes blank after displaying a Fatal Error message (see below) ! I have no idea how to solve this problem.
When I waited a few minutes, my website works again.

Does anyone know what goes wrong, and better: I can I prevent this error?

Fatal error: Call to a member function on a non-object in /data/www/customers/94641/www/class/theme.php on line 499

The fatal error should be fixed by installing Extended Profiles.

I'm afraid I dont know what causing the warningmessage
"Warning [PHP]: in_array(): Wrong datatype for second argument in file include/common.php line 24"

Rest of the messages is only notices and nothing to worry about. You can deactivate PHPDebug from system preferences.

Thank you for your reply, but Extended Profiles is already installed.

It's really weird: De Fatal Error only happens sometimes...

I'm getting this message also. It's enough to give someone a heart attack! I almost passed out. The site was working fine when I logged out last night. Now, it won't let me do anything!

Does anyone know what causes this? Better yet, can anyone help fix this???

I haven't recovered from the shock of seeing this message!!

*Edit*
I found out what the problem is. This happens when there is a problem accessing the database on the server. Host fixed the prob.

hrm... very similar to my fatal error. It happens randomly, and always works when i resubmit the page (after loosing any text entered)

line 125 ... i want to kick it
