I am having a problem with Xara Web Designer (16-1-1-56358) web pages being viewed on-line in Firefox and Chrome (latest versions) due to an error message which is displayed upon entering the website and opening the home page.

Both Standard Site and SuperSite exports do not work in Firefox/Chrome when viewed on-line, only Internet Explorer (Win 10/8.1/7) is successful.

The web pages display correctly locally when previewed within Xara Web Designer, using the Xara web browser and also with Internet Explorer, Firefox and Chrome.

Any assistance would be greatly appreciated.
