Getting deprecated: Function message all over web page

I've gotten the following message all over a web page:Deprecated: Function eregi_replace() is deprecated in /home/hfqmjsoe/domains/tutsforps.com/public_html/Photoshop-Tutorials/index.php on line 107. The message is all over the site and varies but the deprecated: function is repeated. Is this a problem with my Mac or the website? I am using Mountain Lion. Had logic board, hardrive, processors and keyboard replaced and am wondering if I still have a defective laptop. Yes, I have the 2010 Macbook Pro 15" lemon.

Thanks for any help and/or advice.
