I'm having some basic difficulties understanding whether or not I actually modify a given file - I open them through Smart FTP, and it often asks if I want to overwrite or skip - but then asks me again the next time I open it. This last time, I copied to my desktop, and back, and seem to have knocked out the entire site. We're losing money at a phenomenal rate when it's not up, and I have no idea how to restore it. I tried (I think) to replace the file I modified by dragging and dropping from an earlier backed up version to the FTP folder, but this seemed to do nothing.
http://trouncerecords.com will show you the errors. I'm not sure how to check to see if I added blank lines, or how to successfully remove and save the file if I did. Any help would be greatly appreciated. Errors are below:
