I'm using this plugin to give the possibility to users to change theme individually.
Now i want to delete a theme i was using, but trying on my computer i realize that if i am using that theme (selected on the plugin dropdown list) and the admin erases that same theme, when i enter the blog it shows a blank page. I erased all the history, cookies and cache from Firefox and i still just get a blank page. So, what i need to know is how to erase a theme and make people that were using that theme enter the blog on the main theme.
Thanks in advance for any help/suggestions
