All installed well, however: plenty of Warning: fopen(... type errors

Al installed ok, but am getting the following:

System: OS X Leopard server 10.5.4, PHP 5.2.6

Any ideas how to resolve this problem?

Cheers

Looks like a permissions issue for your cache directory.  What is is currently set to?  If it works OK with 0777 then that would confirm the cause but you might want to tighten permissions a little in combo with ownership rights if this will be your public webserver.  If it's only local for testing it's not so critical, of course.
