Getting error message with code

[niclaw]

So, I got this piece of code from a developer. He is now unresponsive.

When I paste this code in the functions.php file and try to save the file, I get an error :
"Something went wrong. Your change may not have been saved. Please try again. There is also a chance that you may need to manually fix and upload the file over FTP."

Can anyone have a look and help with the code?

There is also a chance that you may need to manually fix and upload the file over FTP.
