Having seen many recommendations for Super Cache, I installed and set it up, only to find it didn't work with my theme (Widescreen by GraphPaperPress) and all of my menu/navigation had vanished.
I didn't realize there was a different way to un-install from most plugins, so went in and hit "deactivate" and then "delete". I got a bunch of error messages (cant replicate now unfortunately) and the site was still broken.
I logged into my file manager and went to wpcontent/plugins and manually deleted the SuperCache folder - still no joy.
It's only now, after much googling, that I've found there was a specific way I should have un-installed... which is all a bit late for me, and my site is still broken.
I have put in a support request to my theme developers, but am also appealing here for anyone who could help. My site is http://www.mayuphotography.com and I'm running WP3.0.1
