I found the following error within the db.php file. The insert query was throwing up errors. I removed the id field from the query since no value is being added to it and it fixed the issue.
$galleryslidequery = “INSERT INTO” . $wpdb -> prefix . strtolower($this -> pre) . “_galleriesslides(id,slide_id,gallery_id,created,modified) VALUES (”, ‘” . $slide_id . “‘, ‘” . $gallery_id . “‘, ‘” . $date . “‘, ‘” . $date . “‘);”;
and change it to:
$galleryslidequery = “INSERT INTO” . $wpdb -> prefix . strtolower($this -> pre) . “_galleriesslides(slide_id,gallery_id,created,modified) VALUES (‘” . $slide_id . “‘, ‘” . $gallery_id . “‘, ‘” . $date . “‘, ‘” . $date . “‘);”;
