I was trying to download the mp3 player (see below ) added this script to header and footer and lost my whole forum --unable to logon to undo --i am a beginner and have no idea how to restore -https://scmplayer.co/
it told me to enter this code into the header -footer  i did but the whole site went blank --called friends and they are unable to log on -i cannot get back to the header -footer ----ps i am such a beginner i dont even know what a header footer is --
thank you
