This error message occured when trying to post to http://amariahart.com/admin/ManageArtists.aspx
Is ManageArtists.aspx the file where I can find the problem code in or would it be in ManageArtists.aspx.cs?
I can attach code/file for either if you like.
I am not a coder I am using an admin to post to my website. I am trying to break down my problem into small questions so someone will help me.
