SyntaxError: unterminated comment

I was able to fix.
The theme developer use comment like below:

/*///////////////////////////////////////////////////////////////////////

which was minified in below:

ahh … the things developers do …

it actually was the JS minifier complaining there’s something wrong with the original JS, as you found out. is that from a theme on www.ads-software.com?
