No template on iphone

I installed JM in my website www.tucsonsbestnews.com i reinstalled 2 times but no changed now is default configuration.
Any help on this. I installed JM in other websites works perfect but not in this website.

Check that PHP has write permission for administrator/components/com_mobilejoomla/config.php.

Hi
Thanks for reply i gave 777 right to config file and all other files related to MJ in components, module, plugin, and templates
still no luck on that.

This problem solved. The problem was background image plugins i disabled the plugins now works perfect.
