I am getting this error on IE8; it is working nice on firefox, and I have to support IE.
I found this page: http://www.nabble.com/Error-with-BlockUI:-%27parentNode%27-is-null-or-not-an-object-td22990094s27240.html And they identify as the problem occurring here: The error occurs in the 'install' function right here: <quote from link> var node = msg.jquery ? msg[0] : msg; var data = {}; $(el).data('blockUI.history', data); data.el = node; data.parent = node.parentNode; <--- ERROR OCCURS HERE </quote from link> Where it talks the problem, and I believe I have run into the same error. The problem is that I can't figure out what I am supposed to do to fix it :) Any pointers on how to fix this so that blockUI can work nicely with IE?
