Removed WPtouch but still in use

You may need to manually delete all cached files from your server via FTP. Once they have been deleted and the cache purged (including the device cache), there will be no old instances of the mobile theme available to be served to desktop browsers.

To configure your caching plugin not to cache mobile pages nor to serve cached pages when mobile devices are detected, enter the user agents found under Advanced Options > Custom User-Agents to the “rejected user agents” areas in your caching plugin’s settings.
