Thanks for the quick response.
Just found out it was because of a plugin called social sharing toolkit.
This fixed both problems
Thanks for the quick reply,
I already tried to do this. but it seems not to work.
Now the color will only fade in when i remove the mouse again
from the tumb. you can see what i mean.
So the thumb is greyscale, when i move the mouse on top of it. its
still greyscale, when i move the mouse of the tumb then there is color.
What i want is, thumbs are in color, when mouseover it’s in greyscale.
Thanks in advance,
