Hey Andrew – I have upgraded yesterday, from 2.3 to 2.7 – and i have a .js that quite too. Have you found any help on this? The only response i am getting is the sound of crickets.
Are you guys talking about Javascript strictly speaking or about jQuery (or some other library like Prototype)? If you are talking about one of these libraries, I’m not sure which libraries changed between 2.3, 2.5, and 2.7 but its worth thinking looking into. A change in the libraries could break you script.
If it were me, and I were having Javascript problems the first thing I’d do is see what Firebug has to say about it. So get yourself a copy of Firefox, install the Firebug AddOn, load your page, and see what kind of errors you’re getting.
