[Plugin: WP Super Cache] after enabling wptocuh showing default theme as mobile even in desktop

I have recently enable multisite in wp-config to check is it work or not , after that have disabled it. Now I am facing the problem that in desktop even it is showing default as mobile theme. I have again disabled and enabled mobile support and wptouch plugin and update mod_rewrite rules, but it have not resolved. I think there is some thing with .htaccess file problem. So that i have disabled mobile support.

Previously it was working fine, in mobile it was showing default as mobile and in desktop showing as desktop theme.
