I am getting this error if I turn my block caches on. I have traced back the origin back to Drupal core form.js but can't seem to see what's going on here. Any ideas?
Here is the debug:
form.js?v=7.56:69 Uncaught TypeError: $.cookie is not a function at String.<anonymous> (form.js?v=7.56:69) at Function.each (jquery.min.js?v=1.7.2:2) at HTMLFormElement.<anonymous> (form.js?v=7.56:67) at Function.each (jquery.min.js?v=1.7.2:2) at $.fn.init.each (jquery.min.js?v=1.7.2:2) at $.fn.init.$.fn.once (jquery.once.js?v=1.2:55) at Object.attach (form.js?v=7.56:65) at Object.<anonymous> (drupal.js?p3kpc3:76) at Function.each (jquery.min.js?v=1.7.2:2) at Object.Drupal.attachBehaviors (drupal.js?p3kpc3:74)
Update: I think I am isolated this problem to a webform in a block on the page. If I get rid of that form, the error goes away. Also, this error doesn't happen every single time. Sometimes I have to change browser or open in incognito for it to crash, and then it happens repeatedly.
I can see that jquery.cookie is there when it works. But when there is a crash and I see the page source it's not there, so somehow it seems it's failing to load and when it happens I get the error. I am using JQuery Update (1.7).
