Where is functions.php

Never edit functions.php of your theme using the built in file editor…ever…one error and your site will break – install and use an FTP client such as FileZilla, first backup site – then in that backup will be theme functions.php, use a plain text editor worthy of this task such as NotePad++ and edit the file then saveas a new name – upload edited file with new name – rename functions.php on remote server to old-functions.php, rename uploaded file to functions.php (load site to test all functionality – test all functionality – yup gonna say it again – test all functionality – note: never use server caching while editing site files.)))

Now – if that edit does break the site guess what you can do in 5 seconds? upload original backed up functions.php ..

And..and..since we renamed functions.php on remote server, if the lights go out, we get hit by a tornado or a flood..the original file is now in two locations..remote and local…since one is ruined….use the other! then back that up again! Of course if your remote server and your local install are by that river…well… you are **rewed!
