I can tell what was happen. I only updated plugins.
Now I repaired it.
As you’re suggested I changed owner to the directory tree and rights and all now works.
I’ve removed manually all galleries created from last 2 plugins upgrades and rebuilt images base. This helped.
I think that reason of this situation can be a bug you’re made in the previous version of the plugin (with “array()”) – I had to recreate manually some files and possible that I did this with another user (on the filesystem).
