Hi everybody I did a fresh install of dnn 7.2.0 on a go daddy shared sever. Everything was fine until I needed to edit something in host settings. Any help would be greatly appropriated. Here is the error message I get on the page:
A critical error has occurred. Object reference not set to an instance of an object.

Here is the log for it:

and here is some more info on what I have (dont know if it is needed)

Thank you for the response, I ended up deleting all the files and reinstalling. It works now. I'm just guessing here but I think that I may have forgotten to check the permissions on a folder, but I don't know for sure. but thank you for your time!
