I'm using http://validator.w3.org and there seems to be quite a lot of errors! is it usual to have many errors or should I try and fix them all?
One of the errors is, if you look in the source code for any of my pages and find the rel="shortcut icon" there are two links, one is to the old favicon when it was a local site and the other to the live one. Why is there two and how can I fix this.
ps. My local site only has one, only when I uploaded it's gone to two.
