What does it mean when it says' Check gas cap' on the dash

Hi,

Had the above wording (or similiar) come up on my dashboard a while back but not anything to do with the filler cap. 

 

Now engine mangament light is on all the time. Clear engine mangement light and after a while the same comes up on dash,

 

Is it a fuel purge system problem and what's the easy fix?

 

Thanks in advance

Andy
