the shadow of free addons ?

I upgraded to WP 4.0 with qtranslate and i had to apply a manual patch to make it work. As the plugin is no more maintained this is the only way to make it work.

I’m going to test mqtranslate (a well maintained clone to qtranslate) to see if there’s no compatibility issue. hop it helps.
