Hi. I'm attempting to install Social login. I am a complete beginner. I have managed to follow the steps up until step 3 Actions, Hooks & filters. Where do I copy & paste the code in the example? I am unable to see a logical place in functions.php where this should go? I attempted to put it at the end of the existing codes and it corrupted my DB and my site went down. Would someone please be able to help in regards to how I follow the next steps to install Social Login. Thank you!
