Hi,

I've just moved a DNN 8 site from my local machine to a hosts server.

There are a few issues, one is that the jQuery/Ajax call to a web service fails.

In case it helps, I've included a snippet of code below and commented the error option which is executed.

The error message isn't very useful: '[object Object] error Not Found'. I assume this means the web service is not 'seen' by the client.

This code has been working both locally and on a hosted server for several years. I can only imagine there's an issue on the server which I don't have full access to.

Anyone got any ideas as to what I could check? Is there some option in the DNN settings that needs to be set for example? I don't remember one to be honest.

Best Regards,

Steve

                }

                else {

                    alert("File:ContentMainSettingsUserControl.js\nfunction: RefreshContentSettingsMain\nAn error occured - unsuccessful web service call");

                }

            },

            error: function (XMLHttpRequest, textStatus, errorThrown) {

                 //** THIS IS THE LINE THAT PICKS UP THE ERROR

                alert("File:ContentMainSettingsUserControl.js\nFunction: RefreshContentSettingsMain\nMessage:" + XMLHttpRequest + " " + textStatus + " " + errorThrown);

            }

        });

Steve,

Are there any errors in the logs in /Portals/_default/Logs when you hit the page that causes the error?

Hi Scott,

Thank you for your reply.

I've checked the log files. No errors are written when I open my app, nor are any entries written when I try to access the url for the web service directly from the browser.

But there is an error listed caused by accessing any page, please see a sample listing below.

I've also included a list of 'OTHER ERRORS', please see below. But these haven't occured since yesterday, not long after the site was installed and I'm unable to reproduce them now.

The DNN version is 08.00.04 (226) by the way.  Also I noticed the hosted site is using .Net Framework 4.5, but that my local machine the site is using 4.6.
I can't imagine this would cause an issue though, since both are supported according to:
https://github.com/dnnsoftware/Docs/blob/master/main/DNN8-Requirements.rst

Best Regards,

Steve
