A little knowledge is dangerous

I have been attempting to make a site responsive. I used Brackets to create my code and all went well. When I put it on my site, I got the following error at the top of the page, then it loaded as I wanted. I suspect my code is fighting existing code but have no clue how to fix. Error only shows up on smart phone

window.onload = function() { if(!window.location.hash) { window.location = window.location + '#loaded'; window.location.reload(); } }

site address http://www.oregongardenclubs.org/

Comments welcome on my coding
