gallery

Hello!
I have a problem I can not solve.
I had to disable all my website plugins because I could no longer access the WP php page.
After the problem was resolved I plugged in plugins one by one and everything came back perfectly as before except the gallery.
In ” Album Photo ” albums and sub-albums are all present.
In the template menu I see ” Some menu items are invalid. Check or delete. ” And I do not know how to do this to make the gallery visible.
Thank you!
