This plugin allows you to modify/switch the current theme on the live site without interfering the current visitors.
= Why using this plugin I can modify the live theme on the fly?= This theme allows you to duplicate current theme and modify the duplicated theme. Then the theme switcher will be available to the specified set of users in frontend. All other visitors cannot see the theme switcher and the wordpress instance will still use the current theme until you explicitly switch over to the newly fixed duplicated theme.
Either admin user or the user whose ip is listed in whitelisted IP addresses list.
= What does Whitelisted IP Addresses mean? The ajax theme switcher will be available to these IP addresses which get whitelisted in backend.
= What should I do after the I finishing modifying the duplicated theme?= Once you make sure you have fixed all issues with duplicated theme then just choose the duplicated theme.
Please make sure your theme directory is writable to web server user or the target directory doesn't exist in the system.
