Not sure why, but Ajax stopped working in DNN 4.6.2.  It may have began when the site was backed up and restored to a new server, but I am unsure whether it happened before, during, or after the transfer to a new web host.  Specifically, Ajax no longer works in FAQ module even after reinstalling that module - the "loading" message appears but not the "answer" it is supposedly loading.  It also stopped working in Catalook.net Store modules.  It does work fine in ListX modules, and I've wondered if ListX had caused any problems, but, I have the exact same install on my local machine and Ajax is working fine in all these modules, so I don't think it was a problem caused by ListX either.  Since we are using Catalook, we cannot upgrade to any more recent version of DNN, Catalook versions are DNN version specific and the version we have will only work with DNN 4.6.2.  It appears Ajax is set up fine in the web.config file.  There are no errors or event log entries reporting any problem.  The Ajax postbacks just initiate but never complete like something is missing, except for the ListX modules which Ajax works perfect in.  What would cause Ajax to just basically stop working altogether?

Thanks for any advice or direction,

Rick
