When I go to switch the theme, a few minutes later when I go back to edit the theme it says "The requested theme does not exist. Then I have to go back and re-select it because when I go back to view themes, none of the themes are selected. This is strange. Has this happened before to anyone else?
The problem is, when a theme is not selected, most pages on my site are blank (just a white screen without words).
Here's my site URL: http://suefeng.com
