Build a Website

I am Facing a bug in my website([login to view URL])which i developed by someone from up-work. I don't know much about the [login to view URL] problem i was facing is that on the home page the top most add i placed is not working! When i check it by clicking on it many times, it is showing some error and nothing is opening , check the website this same error is happening on all the posts, have a look on 2-3 post's adds .Bid only when you can solve the bug .Because This Problem is not getting solved permanently that's why i give the link above that you can examine the error. while bidding , mention "Google's Adds Bug" so that it shows you have read all properly.
