Uncaught Error: Object of class WP_Error could not be converted to string

That’s not related to the plugin. That’s your theme’s error.
Could you elaborate, and give a little more info.
Dan.

Thanks for reply Dan, yeah it’s actually in the backend products menu – everything else seems to work fine, but the products screen is broken. screenshot here: https://ibb.co/xLdMTK3

Hi,

I might have an idea what is causing the issue, but I would need you to edit the plugin and comment out 2 lines of code, one at the time.

If you go in the plugin editor and select /includes/RafflePlayWoo_Plugin.php
Comment out line 259 first:
add_filter( 'manage_edit-product_columns', array( &$this, 'drp_add_product_column' ), 10, 1 );
Save and have a look if error persists.
If error still there comment out next line 260:
add_action( 'manage_product_posts_custom_column', array( &$this, 'drp_product_column_raffle'), 11, 2 );

Dan

Thanks Dan,
Commenting out the first line worked thank you!

Great.

Will do a release ASAP.

If you like the plugin, would appreciate if you could rate it.

Thank you.

Dan.
