Just a white page

Hi,

What version of WordPress and WPtouch are you running?

You may want to check if one of the active plugins in WordPress is conflicting by deactivating them one at a time in the Plugins page in WordPress and see if you find a culprit.

You can start with the plugins you suspect may be causing the issue, if you have a large number of active plugins. If that fails to work, please briefly activate a default theme like the 2013 or 2014 to check if the desktop theme is causing the issue/conflict.
