One thing I forgot to mention yesterday: I updated My NextGen Gallery Plugin and placed WP-eStore.php back into the View folder of NextGen Gallery. I checked the Web Page and it was displaying the Gallery in Grid View. Then I used the short code
[nggallery id=1 template=wp-eStore-auto-addtocart]
afterwards the web page would not display my gallery in grid view with and without the short code.
