I tried this and this and this and this and countless other searched terms for getting a 500 Internal Server error. Using F12 developer tools on the browser and when the dropdown need to fetch the next dropdown's data (i.e the GET) then I get this. $ GET http://webserver/app/Home/GetConstituenciesList?Region=13 500 (Internal Server Error) This code is also present: 0x80070005
I have a IIS web server, 2016, worked 100%, no issues, no problems, my project worked 100%. Then, I added a extra field and published and it suddenly gives me these errors.
