After updating the WordPress version 5.5 and updating the Grid Kit the galleries are all disappeared! I had to go and restore WordPress to the previous version and restore the whole website to an earlier time (and lost all the changes that we did on our website) to make the galleries work again! I am paying for the updates so, I am wondering what am I paying for if you are not updating your plugins! All my other plugins had been updated but not yours! This is not acceptable! Here is what it shows when you check the details under installed plugins:
