Hi,
I see that the options framework it’s not displaying fine.
I tried to went to the plugins but I couldn’t because received an error message that indicates that the server is running out of memory.
Don’t know what are your WordPress memory setting but you can change them in wp.config.php in the root of the site.
http://docs.woothemes.com/document/increasing-the-wordpress-memory-limit/
Also in the same wp-config.php can you turn on the debug by changing this line
define('WP_DEBUG', false);
to this one
define('WP_DEBUG', true);
Also check your servers logs to see if there is any additional info that help us solve this issue.
