Unable to log into SF5.3 with IE11

Hi,

Since upgrading to Windows 8.1 I am unable to log into my Sitefinity 5.3 with IE11 in Edge Document Mode.

IE11 popped up a debug mode and had the following error message:
'WebForm_DoPostBackWithOptions' is undefined.

Our website also has a members log in section via the Sitefinity login widget which also doesn't work with IE11.

I am not a developer, but just wondered if there was a quick fix for this on the client side?

Many thanks,

Rob

Isnt this the problem to do something with your server missing an asp.net patch for IE11 browser detection or something?

Hi Steve,

Thanks for getting back to me so promptly and with a possible solution.
I will pass on your comment to our developers... they might be able to understand and do something about it :).

Thanks again, I really appreciate the feedback.

Rob
