When opening certain web pages (those that contain forms, like this one: https://www.citaprevia.sanidadmadrid...ms/Acceso.aspx) , I get the following:
**** Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 12002 ****
and the page not open.
I get the same message when I try to open with Chrome, IE11 or Edge.
This happens since I upgraded to th2.
Any idea? Any help?
Thanks in advance
