WordPress MU

Hi there

Just upgraded from WPMU 2.7.1 to 2.8.1.
I've got subdomains set up on a XAMPP install on localhost.

Now whenever I try to change themes (via the Appearance feature in the Admin Dashboard) the themes that are available take ages to appear. And when I try to display other pages containing themes (e.g. next page or jump to page 3, for example), WPMU takes ages to load them up - most of the time I simply get a blank screen or the system times out: "Maximum execution time of 60 seconds exceeded..." or this message appears "Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 1854941 bytes) in C:\xampp\htdocs\wordpress-mu\wp-includes\http.php on line 287" when trying to load the Appearance screen.

Any idea why this should be happening? I didn't encounter this problem in 2.7.1. Has anyone else had this problem?

Are you connected to the internet at the time?
Try this plugin and see if that speeds things up a bit:

Thanks for the tip, cafespain. I installed the plugin you suggested and everything in my WPMU set-up loads much faster.

I still encountered some time-out problems when I tried to view/apply new themes (which is probably because I've got around 300 different themes loaded!) so I removed some themes and modified the wp-settings.php file, increasing WP_MEMORY_LIMIT from 32 to 64MB. This seems to have done the trick.

Thanks again for your help.

Yep, that'll do it! :D

My local install is the same.
