I have this trouble and already read lot of topics but I did not find any solution.
Examples with a click I have this (working local) http://localhost/wo/?page_id=9
nothing load the index.php
except (strange) my internal links to gallery2 (I have wpg2 plugin).
I tried with other themes, with plugin desactivated it's the same.
Everything is okay but not this !
Plugins : utw and wpg2
Thanks in advance for your help and sorry for my bad english (I'm french).
