Hello,
I have run into some odd problems in the past few hours.
I run a wiki at http://www.eng.uwaterloo.ca/~syde08/wiki
As you can see, it is not displaying the Monobook template properly. This problem occurred after my server admin upgraded their PHP and MySQL services. The odd thing is that the Cologne Blue, Classic and Nostalgia skins all work, but I don't even get the option to switch to Monobook when I go to my user preferences. Can someone shed some light on what is happening? I will try to provide whatever more information you need.
Thanks,
Taneem Talukdar
