Rig controls detached from mesh

[gpasong]

I done goofed up and must have deleted the wrong thing/unchecked a box I shouldn't have, now when I rotate/translate or otherwise edit the controls for the rig it has no effect on the mesh - see screenshot. I have 2 different rigs and both are suffering the same problem.
I don't have any file backups or anything so I really need to know if there is a fix to this. I'm pretty new to Maya so I'm hoping someone more experienced can point me in the right direction as to what I did/ how it can be fixed.

Thanks for your time.
