Ok I finally got the server issues straightened out and server audit has NO Fails. However, now when I attempt update, I receive the following message:

Can't apply upgrade because the following files were modified: studio/template/images/spl-image-main.svg, template/images/spl-image-main.svg

This might be the only thing I changed on this install. Why am I getting this message, with no options for bypassing? I have everything backed up but it's not asking me if I did that. This is maddening!
