hovering over images/titles bug

hi everyone,

I’ve finished setting up an arabic blog (gaminguru.net) with this theme and everything was working fine until all of a sudden i started getting a weird bug when i hover over the posts’ images/titles in the main page. the title disappears and a popup of it shows up at the top of the image. it’s a little hard to explain so you’ll have to visite the website to understand.

I haven’t added any plugin that might interfere with this but i’ve tried disabling the last ones i installed but nothing changed (the last ones being: “Special Text Boxes”, “Fast Secure Contact Form” and “NextGEN Gallery by Photocrati”).

ANY help would be more than appreciated as i’ve been banging my head since yesterday and i can’t, for the life of me, figure out a solution or what even caused this in the first place!

Thank you in advance.
