You can’t create topic on the XStore Support forum because you need:
1) Extend support period.
2) Register code on My account page http://prntscr.com/jcolsg
Once you do this go to Xstore support forum, create the topic, provide us Dashboard and FTP access to your site. Also, tell us what option do you try to change? Because there are many settings in theme options? Which one does not work?
