Thanks for replying so quickly.
I’m working on getting root access to the wp-installation so I can get more debugging tools going. I’ll try out some debug plugins as well.
Will post my results here.
The site I’m having problems with is an ‘inherited’ job, so it’s developed by someone else, and I believe the problem lies within either a heavily customized twentyten theme, of even hacked core 😮
About the version. I installed your plugin on 3.5.1, and updated to 3.5.2 – didn’t help.
Cheers!
