WPtouch detects IE8 as mobile browser

It’s not really possible.

Likely you’re using a cache plugin which has not been configured to exclude the user agents WPtouch uses.

@samuelaguilera – check to see if your list of custom user agents includes anything with the string SIE or similar. If it does, delete that entry from your list. I had this in my list to match Siemens mobile phones, but the plugin will also match the string to MSIE and display the mobile version.

Other people have had problems with some redirection plugins, so you might check that too: https://www.bravenewcode.com/support/topic/urgent-desktop-version-redirects-to-wptouch-mobile-landing-page-cant-fix
