I'm not sure if WebDav is the issue, but here goes:
We have a DNN (4.8) intranet that has experienced no problems at all. DMX 4 installed just fine, and I confirmed the installation per the installation documentation. One strange thing did happen yesterday - after I first put a DMX module on a page and logged out, my home page showed an error regarding AJAX script manager. After doing some research, I restarted the DNN application (Host, Settings) and all seemed fine.
Today, however, something new has developed. On every page of my intranet, the bottom right corner tells me I am in "intranet zone", but when I add a DMX module to the page, it changes to "unkown zone (mixed)". In addition, the DMX module is empty, only showing the "frame" of the module. I can get to the module settings, but nothing there seems to point to this issue.
I'd appreciate any help you can provide. Thanks!
