Error after Install

I installed your plugin and haven’t tried using it at all, but I did activate it. Since then I am seeing tons of these messages in the error log:

PHP Warning: include_once(): Failed opening ‘fields/acf-photo_gallery-v5.php’ for inclusion (include_path=’.:/opt/cpanel/[deleted for security reasons]/root/usr/share/pear’) in [deleted for security reasons]/public_html/wp-content/plugins/navz-photo-gallery/navz-photo-gallery.php on line 83

Please help! Thanks.
