Can't save anything in theme option page

Hello I'm running Wordpress 4.4 and I bought Catch Box Pro premium (4.3.2). When I try to modify values in the page "theme options", it seems that nothing is saved (but strings are written in the database, table wp_options). Could you tell me if there is something I can do? Rights problems somewhere? Thank you in advance Best regards Guillaume (the website is http://mryome.com)
