Okay I did the 5.1.2 update.
Upgraded PHP to 4.1.2 per the how to withouth a problem (brownfamily)
Upgraded doing the IMP upgrade via the howto about not being able to delete a folder.
When I go to my IMP webpage I see this error. Any ideas?
Warning: Failed opening '/home/httpd/horde-phplib/prepend.php3' for inclusion (include_path='.:/home/httpd/horde-phplib') in Unknown on line 0
