Hey Donncha, we’ve been experiencing some strange problems with the interaction between wp-mobile-edition and wp-supercache. I’ve carefully checked that all the .htaccess files are correctly written and the mobile support option is checked but we are still seeing some posts getting cached in mobile format and shown to desktop browser users.

I’m going to do some more testing with the debugging, but was wondering if you’ve been hearing about this from other people or have other advice?

Maybe a solution would be to just block all mobile user agents from caching in the “Rejected User Agents” section? Would that work? Maybe just set the DONOTCACHEPAGE constant at ‘init’ if the mobile edition plugin claims its a mobile page?
