profiling a page with update panels

I'm trying to track down a performance problem with a legacy asp.net site, however I'm getting an error clicking any of the buttons:

Hi,

ANTS Profiler breaks websites for a few reasons like permissions, code access policy changes, and failure to read the configuration properly. Unfortunately the symptoms are always different so it's impossible for us to construct any KBs that will help and therefore you won't find anything this specific on the website. Problems like yours have to be debugged individually.

I'd assume the reason for this message is that the server is returning an error response instead of the expected XML data that the control should be getting from the server. So ANTS more than likely has broken the configuration and caused an exception which is being concealed by IIS.

So I guess what you can do is use Fiddler or a packet analyzer to work out what response is coming back from the server (details about the actual error are probably in the response) or attach a debugger to see what the errors are. Then we have to take a few stabs at working out how ANTS Profiler managed to misconfigure the site or break the code.

Do you need any further assistance to work out how to debug the website? Unfortunately you cannot get the failure cause from anywhere in ANTS Profiler like the log because the error is happening in the application.
