unable to create gallery

Hi

I’m trying to migrate webpage from localhost to server
After I’ve installed Final Tiles Grid Gallery Lite and check if everything with page is ok I recived following error log:

Warning: Creating default object from empty value in /wp-content/plugins/final-tiles-grid-gallery-lite/lib/db-class.php on line 93

So i tried to create new gallery as usual. Unfortunately after choosing pictures and saving gallery there are no galleries. I can again see screen with info “Create your first awesome gallery, click here.”

On localhost it’s working (the same version)
