Warning: Error in parsing value for 'display'. Declaration dropped. Line: 0

Question

Warning: Error in parsing value for 'display'. Declaration dropped. Line: 0

I'm not sure what happens when I leave this warning, because I don't see any strange behaviour in any of my pages.

Still I want to remove it just in case, can anyone help me try to find a solution? Thnx

EDIT:

I just noticed an error in my php script, which caused my object to have style=display:; Now it's solved, thanks a lot!

If you don't have too many hacks and overall write neat CSS, try a CSS validator.
