Set the color of your visited links by adding the css below to your css stylesheet, replace 'whatever;' with the color you want your visited links to be.
I said that i already changed the a:visted link color in css but it isn't changing it to the color i set it to.
We need more information to be able to help you.
Either post your code.
Or, preferably, upload your problem page to the web and post a link so we can view it in our browsers.
Depends largely on WHERE in your CSS you changed it. Without seeing the code though, there's really no way to know.
Could be something as simple as one too many }s in the whole page too. I've seen that negate EVERYTHING below it in the code.
click ctrl+j while on that page in dreamweaver (or go to modify>Page Properties...) and try changing it there. If it is a problem with the CSS that might fix it, and it may make it easier to change them.
