    That’s encrypted code, and usually it’s proof of a hack. That code looks like this: http://cl.ly/image/1s3B063f091i

    It’s extremely bad practice for many reasons: obsfucated code, advertising links. I’d recommend you just get a new theme from https://wordpress.org/extend/themes/, and tell the developers of your current theme that they suck.
