I've just installed Personas SP02 and all has gone smoothly apart from one little glitch. It seems that the "restgui" service in SICF is replaced (or at least updated) by the service pack installation, and the new one isn't quite right. In particular the handler is set to CL_HTTP_EXT_ITS rather than CL_HTTP_EXT_ITS_BASIC. Note that this was correct in my system before I installed SP02. You find this in SICF, here:
If your system stops working after applying SP02, check this first!
After fixing this I've had no other problems but I've not tested extensively yet. I just wanted to get this info out quickly before anyone else wastes time tracking this one down...!
