Your attempt to switch to this theme: “” has failed.

Hi all,

I installed the wordpress script in my server. Everything is okay, but when i’m unable to change to any themes, even the default one. Currently i’m only restricted to the default theme.

The themes that i’ve downloaded appears in the design tab, however, when i choose to use anyone of those, the error message “Your attempt to switch to this theme: “” has failed.” appears. Pls help!
