Since twoday's update of the plugin Easy FancyBox  to v1.5.0, there is a compatibility issue with the plugin WordTwit  v2.6.4. When both of them are activated, article editing doesn't work correctly in WordPress anymore: The text formatting buttons are not displayed anymore, and it is no longer possible to use the links for changing date and time or show tags etc. This is very annoying, of course.
Both plugins worked well together until recently, so it is clear to me that the issue was caused by the update of Easy FancyBox. However, I can't tell if the "bad guy" is Easy FancyBox or WordTwit, so I'd like to kindly ask both programming teams to search for the collision cause. Thanks!
