All the wordpress blogs that I do maintenance for have the Super Cache plugin installed. However for some reason one of the sites keeps locking up when it’s enabled, despite a nearly identical site by the same author not having the problem. At least not at this time.
I’ll wait for an update or bugfix to coincide with the current Wordpress version before trying to enable it again. If it’s really just a problem with the php/web browser configuration, why has it not affected the other sites?
