I am facing the PageRequestManagerServerErrorException here's the exact message:
Error: Sys.WebForms.PageRequestManagerServerErrorException: An error
occurred while executing the command definition. See the inner
exception for details. ScriptResource.axd:29603:2735
And the inner exception is following:
Type.registerNamespace('Sys.WebForms');Sys.WebForms.Res={"PRM_UnknownToken":"Unknown
token: \u0027{0}\u0027.","PRM_MissingPanel":"Could not find
UpdatePanel with ID \u0027{0}\u0027. If it is being updated
dynamically then it must be inside another
UpdatePanel.","PRM_ServerError":"An unknown error occurred while
processing the request on the server. The status code returned from
the server was: {0}","PRM_ParserError":"The message received from the
server could not be parsed. Common causes for this error are when the
response is modified by calls to Response.Write(), response filters,
HttpModules, or server trace is enabled.\r\nDetails:
{0}","PRM_TimeoutError":"The server request timed
out.","PRM_ParserErrorDetails":"Error parsing near
\u0027{0}\u0027.","PRM_CannotRegisterTwice":"The PageRequestManager
cannot be initialized more than once."};
Weird thing is that I am getting this error on production but it's coming on QA or Development and all of my code is same.
