I am stumped. At this moment I have a significant number of issues that all appear to be related to either AJAX or the above resource file.
This issue occurred sometime after I had my hosting (PowerDNN) upgrade my DNN Install to 5.6.1
They have proposed rolling back the upgrade, but my understanding is that there were critical updates made in 5.6.1
A summary of the issues:
(Chrome browser)
It started that the Edit Module dropdown failed to load. I would see the "loading" gif indefinitely.
This error was the following:

I did some searching... came across the DNNXMLHttp.js issue, tried their proposed solutions. No avail.
The host tried a couple different things, then switched my App Pool from Integrated Mode to Classic.
I am now able to see the Edit Module Menu.
Start navigating around, notice quite a few issues with my URL Rewriter from Active Modules (it apparently does not like Classic Mode), removed Vanity and Friendly URLS, there ends up being a DNS propagation issue, and App Pool is left in Classic Mode.
It's... sort of working. However, now there are other issues. Postback from Ajax calls fail.
For example, using the ribbon bar, a core function of DNN, when I add a module by clicking the "Add Module" from the Insert Module tab, the module adds, but the page fails to load and the following error is thrown:
