I saw on another post (ACF Pro and Essential Grid Conflict) that someone else had this error, which I am getting on all my sites with ACF Pro and Essential Grid installed. The user in that case stated that everything works OK, but actually, this removes the dropdown that allows you to select an essential grid to use to display your selected gallery.
Although this can be fixed in the HML code where the gallery is displayed (you can add the name of the grid manually), it would be preferable to have an actual fix for this bug.
Are there any updates or fixes?
