“When checking your page in various browsers, you may find Safari displaying a bright red text color for your page anchors (links), overriding the colors you've specified in your CSS selectors.
Once you locate the document returning the 404 error, you can upload that CSS file to the server and your red links will disappear.
Theory is that Safari is erroneously rendering the 404 document (since it's being returned in place of a CSS file) as a CSS document. And thus, the red link selectors in the head of the error document are overriding your own selectors.
Note: This problem only exists on certain servers since 404 error documents will differ slightly. If you create a custom 404 page for your site, it's likely you'll never see this problem (or may see something entirely different).”
