Last update crash my gallery

Hello, after the last update I have a problem with my gallery. There was an update so I made it, after this action the gallery plug disappeared from my wrodpress. The gallery structures on the server remained unchanged. I can’t see gallery in bets or plugin list in my wordpress. In the posts where the gallery was used, only the following entries were made: [ngg src = “galleries” ids = “111 ″ display =” basic_thumbnail “]

How to fix it ?
