Horde Versions Horde: 1.2.3 IMP: 2.2.3 PHP Version PHP Version: 3.0.16 PHP Major Version: 3 PHP Minor Version: 16 Your PHP3 version is recent. You should not have any problems with Horde modules, provided that you have applied the patch(es) described in horde/docs/INSTALL. PHP Module Capabilities IMAP Support: Yes LDAP Support: No MySQL Support: No PostgreSQL Support: No PHPLIB Configuration track_vars: Yes PHPLIB (is page_open() defined): Yes I am now going to try to create a HordeSession class. If this line is the last thing that you see, then you do not have class HordeSession defined in the phplib local.inc file. Fix that before proceeding. Created a HordeSession instance successfully. Click here to test PHPLIB for Horde (If this link results in "Document Contains No Data" or "Fatal error...", then you probably have not defined the HordeSession class in the PHPLIB local.inc file).
