Well, you combine many different stacks from different developers…
Poster Stack works without any problem with Foundation. Just to state that, I tested this several times and have a lot of customers running with that.
That JavaScript error might just be the outcome of some other misbehavior. I doubt that there is an error in Foundation. Best is you update all Stacks to their latest version and test step by step which stack causes the error.
