WebResource.axd not loaded when using latest Google Chrome Browser

WebResource.axd not loaded when using latest Google Chrome Browser

I'm having a strange issue:
I can't login at http://maskatel.info/login, when I try to click the login
button (the blue button that says Connexion), nothing happens at all.
So I opened up the developer tools in Chrome (f12) and saw the following
javascript error everyime I click the button: Uncaught ReferenceError:
WebForm_PostBackOptions
I then found out that this fuction should be in WebResource.axd, I then
went to the Resources tab in the developers tool and found out that this
'file' is not there and it is not loaded in the HTML source.
I tried a lot of different things without any succes and finally tried
another browser and it works fine in any other browsers. That same page
was working perfectly previously in Chrome on the same computer in the
past.
So then I tried to click the small gear in the Chrome developer tools and
went to the overrides section and changed the UserAgent to something else
and refreshed the page and it works perfectly with any other UserAgent
string. The correct UserAgent when not overriden for my browser is
Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko)
Chrome/29.0.1547.57 Safari/537.36
So right now I really don't know what to do next:
Is this issue related to the latest version of Chrome? I have not found
any information on release dates for chrome.
It could also be a DotNetNuke problem but I doubt it since nothing there
changed before and after the problem
It could aslo be asp.net related (I renamed App_Browsers to App_Browsers2
and still no luck.
Any help would be appreciated.
