I need help with the following Problem: When I choose to show the Members of the "Administrators" or any other Group I get a blank JS Alert window and "Error loading Page". I also can't add new groups, when I add one it appears in the Database but not in the CMS.

Basically the following Ajax Call produces a 500/Internal Server Error for every ID but "0":

it does not happen on my local development server (PHP 5.2.5 / MySQL 5.0.51) just on the Webserver (PHP 5.2.5 / MySQL 5.0.41)...

How can I track down the details of that Error? I don't have to much clue about Servers so any help is appreciated. Has anyone had similar problems?

Please Help!

Ok, I got access to the logs, maybe someone can help me with further investigating:

[11-Feb-2008 17:39:03] PHP Fatal error: Uncaught exception 'ReflectionException' with message 'Property db does not exist' in /Applications/MAMP/htdocs/www/sapphire/core/Object.php:318

so does it try to find the $db static for a Member Group and can't find it or what?
Any Ideas?

In case anyone cares or has the same problem: turning off Zend Accerlation fixes this.

Very glad you posted this. I had the same problem and I would have never caught this.

Is there anyway around this without turning of zA? That is indeed the problem with this error though... Strange!
