Has any one come across this problem every time I try to activate a site wide theme change the wpmu-themes.php tries to execute and then try's to down load as a file and the settings are not stored I have Tried to communicate to my server providers they don't think the problem is their end
Other execution scripts work fine its just the wpmu-themes.php that tries to download at this stage
To view the issue the file I am trying to execute is http://freeblog.co.nz/wp-admin/wpmu-themes.php
try to select a theme and execute it ..!
