Links not pproperly escaped

Hi. I have a recently developed online store with some blogs. I have run GTMetrix on some of the pages and I have a particular area that is holding up page load time.... I get a 404 error, and I believe it is because some of my links aren't properly escaped. I am looking for someone to help with this. I believe it is a small job that just needs some tweaking of CSS or PHP, etc... This is a small part of the big picture that I will ultimately be awarding over time. My site ultimately needs many SEO tweaks. I'm looking for a price to fix that error with the understanding that if it done well and reasonably, I will send many more SEO type jobs their way. The error is: Response Headers Date Mon, 25 Aug 2014 16:07:08 GMT Content-Type text/html; charset=UTF-8 Transfer-Encoding chunked Connection keep-alive Cache-Control no-cache, must-revalidate, max-age=0 Cf-Railgun direct (waiting for pending WAN connection) Expires Wed, 11 Jan 1984 05:00:00 GMT Pragma no-cache Vary Accept-Encoding,Cookie X-Pingback http://www.@@@@@@@.com/[login to view URL] Server cloudflare-nginx CF-RAY 15f90a7085860c35-SEA Content-Encoding gzip Request Headers Host www.@@@@@@@.com User-Agent Mozilla/5.0 (X11; Linux i686 on x86_64; rv:25.0) Gecko/20100101 Firefox/25.0 Accept image/png,image/*;q=0.8,*/*;q=0.5 Accept-Language en-US,en;q=0.5 Accept-Encoding gzip, deflate Referer http://www.@@@@@.com/oceanside-summertime-gift/ Cookie __cfduid=dd33a760f64b3863cf72c720fa43896cc1408982827173 Connection keep-alive
