WordPress Gallery short code is missing

Hey There,

Need some assistance with Grid Galleries plugin. I have both “Media Library custom Fields” and “Grid Gallery with custom fields” as needed and up until a week ago,it worked fantastically. Suddenly today I receive the following announcement:WordPress Gallery shortcode is missing. Please add WordPress Gallery to the Grid Gallery”. Anyone has a clue how can I fix it?
