Hello all,
I have the same problem with 31 January application version / 6 february and 13 february versions.
As ccyarm said, there is the trim function who is not recognized... and it's normal.
Why ?
string returned value is not a function.
trim($('#emailresponseto').val()) could works and $.trim($('#emailresponseto').val()) also (function trim is defined into globalsettings script file).
i changed $('#emailresponseto').val().trim() BY $.trim($('#emailresponseto').val()) and all works perfectly now.
It works under firefox it's true but it's not a reason to tell than there is not an error into this script
