I can't save the Theme Options page?

This error occurs because your server limits the amount of data that can be saved at one time. There are two ways to increase this limit:

1) Edit your php.ini file and increase the max_input_vars function to around 3000 e.g.

max_input_vars = 3000;

2) Alternatively edit your .htaccess file (in the root of your WordPress installation) and add:

php_value max_input_vars 3000

If you're not able to do either of these please ask your webhost to do this for you.
