Kentico 7 Bizform submission in IE10

John Fu asked on May 13, 2014 20:13

Hi, I'm experiencing errors when submitting bizforms in IE10 or later on a site we built in Kentico 7. The error is consistently returning "Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500".

This only happens on IE10 and later.

The site can be located at

Thank you. John.

Hello John,

for possible solution take a look at the following forums thread: What is error Sys.Webforms.PageRequestManagerServerErrorException

especially try to add into your web.confg file:

   <add key="aspnet:MaxHttpCollectionKeys" value="8001"/>

Best regards, Martin
