I have a live helpdesk application which was previously running on SP 2010 where the lists periodically update (60 sec) using the standard web part AJAX controls. In the SP2013 solution this same set of controls results in an error.
Unable to display this Web Part. To troubleshoot the problem, open this Web page in a Microsoft SharePoint Foundation-compatible HTML editor such as Microsoft SharePoint Designer. If the problem persists, contact your Web server administrator.
This error has some suggested solutions in the public forums on SP2010 most of which seem to center around the refresh timeout rate which was set to 1 second. there was a cumulative update for SP2010 to allow access to the timeout variable and be able to adjust this value up to a more reasonable value, but so far I have been unable to locate this in SP2013.
Any help, suggestions or advice would be more than welcome.
thank you in advance.
