Not a lot of files! Only 126. By browser console, do you mean like when I double-click the index file? I do get an error when Microsoft Edge pops up that says file not found:./data/system/Config.tjs but that file is there, so I'm not sure what it means. :( And yes it runs fine when I preview it in TyranoBuilder, if that's what you're asking!
I really appreciate all this help, thank you.
