This code is posted on your github and looks like it was recently updated. It doesnt work, but im not sure if its the code, or my website, and am hoping I can get feedback.
What its for:
Its suppose to remove all the tabs on the product-edit page and make it for submitting just an auction.

What happens when using:
After placing the code, a submitted product doesnt show up on the front end. On the backend, under products, instead of showing a submitted product, it places an error on the product page were the product would be. The error itself becomes the product.

Looking at the error I think something is just a little off.

Here’s the error message:

Fatal error: Uncaught Error: Call to a member function get_image() on boolean in /home/runbidse/public_html/wp-content/plugins/woocommerce/includes/admin/class-wc-admin-post-types.php:300 Stack trace: #0 /home/runbidse/public_html/wp-includes/class-wp-hook.php(300): WC_Admin_Post_Types->render_product_columns('thumb') #1 /home/runbidse/public_html/wp-includes/class-wp-hook.php(323): WP_Hook->apply_filters(NULL, Array) #2 /home/runbidse/public_html/wp-includes/plugin.php(453): WP_Hook->do_action(Array) #3 /home/runbidse/public_html/wp-admin/includes/class-wp-posts-list-table.php(1152): do_action('manage_product_...', 'thumb', 78) #4 /home/runbidse/public_html/wp-admin/includes/class-wp-list-table.php(1305): WP_Posts_List_Table->column_default(Object(WP_Post), 'thumb') #5 /home/runbidse/public_html/wp-admin/includes/class-wp-posts-list-table.php(1185): WP_List_Table->single_row_columns(Object(WP_Post)) #6 /home/runbidse/public_html/wp-admin/includes/class-wp-posts-list-table.php(662): WP_Posts_List_Table->single_row(Object( in /home/runbidse/public_html/wp-content/plugins/woocommerce/includes/admin/class-wc-admin-post-types.php on line 300
