undefined array glitch

Warning: Undefined array key "useImageHoverVideos" in
public/wp-content/themes/lay/gridder/projectindex.php on line 335

how do I get rid of this? :)
been trying to fix this for ages, every once In a while it goes away and then comes back covering the menu area (top left to top right of the top section of my page).

and on the bottom it just randomly started showing these pictures from projects :D

can you update lay theme and the imagehover addon?
and clear your cache plugin
