Error when uploading theme

Replies: 1

I am brand new to WordPress and blogging. When I try to upload a theme, I get the below error message:

“An unexpected error occurred. Something may be wrong with WordPress.org or this server’s configuration. If you continue to have problems, please try the support forums.”

I’ve read some of the previous posts around server issues, but it’s way over my head. Could someone please give me some pointers?

Thanks!
