gallery error

[selenoochka]

Hello, I have this problem,
I can not do anything in the gallery, except for adding photos,
I can not create / rename the album, do something in the configuration.
I have a message
Error
Not found the correct key shape.

this happened after I reinstalled version of the Gallery,
but 3 more days gallery worked fine.
Yesterday I had a message, but I reload the page and everything was fine,
and now this error is always displayed.
