When I create a new contact I am getting a "Fatal error: Uncaught CRM_Core_Exception". Maybe this will happen when doing other things too, but I haven't run into them yet. This is quite problematic and prevents me from working with this CiviCRM installation, so I would really to have some help fixing this.
It is a clean install of CiviCRM version 4.6.10 on a clean Joomla! 3.4.8 install with PHP 5.5. No errors were given until I tried to create a contact. Re-installation of everything also didn't help at all.
Full error message:
Sorry but we are not able to provide this at the moment.
DB Error: unknown error
