Hi I am making an ajax call to a page on the change event of a drop down. When I first load the page it works fine, but if I let the page sit for a few minutes then try to change the dropdown it fails and in the console I see this error (I removed some of the unneeded characters in the query string so it didn't take up so much room). The strange thing is, both of these pages are microsite pages. They also both have security enabled in the properties. I added a bit of SSJS to the AmpScript page being called, but it does not help. Anyone experience this before?
