I'm on my first install of Zen Cart 1.3.9h and haven't done much besides some tweaks to get SSL working.

So, I sort of have an idea how the overrides system works, but I did something dumb and am not sure how to fix it. Rather than uploading this theme to the root /includes/ folder I uploaded to /myadminfolder/includes/.

Should I just go into the /admin/includes/ and delete the corresponding files that were uploaded or did I overwrite something important? I don't remember now if I hit "overwrite" in FireFTP or what... guess I was spaced out

I did then upload the theme files to the correct includes folder and it seems to be as okay as can be expected being partway through.
You should go through all of the template files and remove them from the incorrect folder on your server. All overrides were used in the package.

Thanks,

Anne
