Stepped upgrade from 4.5beta6 to 4.50 stable to 4.60 to 4.68. Was as beautiful and eventless an upgrade process as I've experienced. Congrats and thank you team.
My only QA issue is with the civicrm admin menu. It is busted.
I can confirm menujs script is loading.
I can confirm html for the menu is present.
I can confirm there are no js errors.
I can confirm resource urls are fine.
I have cleared the caches like a maniac.
So all I can think of is some crazy css conflict, but I can't even...
Clicking on a link causes it to expand its LI's but incredibly broken-like.
Any ideas would be incredibly appreciated.
