While developing a browser test for bug 60797, I've noticed that some production wikis where VisualEditor is expected to be available do not load VE as expected. In each case, the error message captured at the browser level is (with some variation in the specific line numbers referenced):
global code (load.php, line 1)
- Visit a production wiki where VE is expected to be available, and request a random article with a VE edit param: http://cv.wikipedia.org/wiki/Special:Random?veaction=edit
I'll add list(s) of production wikis where this problem occurs as I uncover them in comments on this bug ticket.
