I recently installed the newest versions of phplib on the php server. We have a calendar system and a webmail system that run off of this server. Of course both of these services use sessions. For some reason once the lib was installed the sessions started to break. When you go to the first page in the calendar you get this error..

Fatal error: Class hordesession: Cannot inherit from undefined class session in local.inc on line 80

After i did some looking i figured out that the calendar was using 'class HordeSession extends Session' instead of the accual session class. So i commented out the the function. Once i did that the calendar worked fine..But the webmail system broke. Nothing is displayed on any page in the mail system. The mail system was created by The Horde Team horde@horde.org. 

I do belive that the local.inc needs to be modified such that a name conflict can be corrected.
