I have installed WordPress 3.2.1 and two themes into my hosting account. One theme was called butterfly and the other clockstone.
The clockstone theme has its own dashboard, but I didn't realize that I could only use that to update the theme. I added menu items using the WordPress dashboard. Then I checked the site none of the menu items were visible.
I was frustrated by this and decided that the theme was too complicated for me to figure out and I attempted to activate the Butterfly theme instead.
Now the only thing I can see on my site are these words:
This theme is released under creative commons licence, all links in the footer should remain intact
I can not get back into the admin page even when I enter the URL
I can get into the files on the server and I could delete either or both of the directories where the themes are located if that would solve the problem.
