Im trying to do a webkit css3 transition however when the link becomes a:visited the transition no longer functions and the webkit inspector would give me the following

How would I diagnose what the alert triangle says, the console is empty in all areas (All, Warnings.. etc).
It only happens when the link is visited
It means there is something wrong with the property or its value (or, that it’s unrecognized).
See what does the yellow color warning icon mean in the chrome web inspector?
