What would stop a 'visited link' on a webpage from changing its color?..

Suddenly, none of the posts which I have visited are changing their link color?? It's happening on DU but on some other sites as well. Any thoughts would be appreciated!

you didn't say which browser you're using but here's how you can check your "link color" settings in IE and in Firefox:

IE: click "Tools" (menu on top of page) then "Internet Options" then click the button (lower left) called "Colors"

Firefox: click "Tools" then "Options" then click the "Content" tab then click the "Colors" button

your "link" and "visited link" colors should not be the same ... if they are, change one ... this will only help IF you're overriding the websites colors with your own selected colors.

it's also possible that you're seeing a "cached" copy of the page (i.e. the way the page looked when you first visited it) ... try hitting your browser's refresh button to see if the visited links change color ...

If you clear your cookies many sites won't "remember you." Your link colors may not update on those sites until you sign/log to that in again. (If you check "remember me" it creates that cookie again.)

However, since you posted here on DU I assume you are logged in. If it's still happening here on DU your problem likely is elsewhere.

I had already tried resetting the link color options as well as deleting related cookies, which didn't help. I'm using Maxthon, which is a tabbed shell browser program based on IE; IE itself is also showing the same behavior. (Maxthon doesn't have this issue on my laptop.)

Updated: I dumped the history dat file; that seems to have done the trick.
