I've recently installed WordPress 3.6.1 to a 1and1 hosted domain (Windows) but I am experiencing difficulties with themes and plugins. The URL for my site is:
When I go to add a new plugin, the following message is displayed:
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 have the same problem when I go to look at other themes. I have tried installing WP several times but I am still experiencing the same problem. Anyone have any ideas as to what is causing the problem?
