WordPress Upgrade equals site issues

Ok So the WordPress updated to 3.8.2, I am using MusicClub Theme from Goodlayers and now, qtranslate doesnt work,that plugin actually crashed my site and with assistance I was able to get my site up again, however the plugin still doesnt work, my revolution slider doesn’t work, my sub menus wont show no matter how much adjustment I have done.

My site is in the coming soon mode, I want to launch but no idea how to fix these issues.

PS I am not that computer savy but I try.

Please help,
thanks
