When I use IE7 to visit a page, I get the uncaught error:
SCRIPT1010: Expected identifier
load.php, line 81 character 619
I think it means that it's tripping over OOjs usage of the super and static reserved words. The only modules using OOjs currently are MMV according to mw.inspect

OOjs supports IE6-8 now, although it's not clear to me from the commit message of https://gerrit.wikimedia.org/r/#/c/140436/ whether it does that out of the box or an ES5 shim still needs to be added by the caller.
