Which lists do the subscribers belong to? If they belong to the WordPress users list you need to delete them as WordPress users from your wp-admin > users for them to be removed from MailPoet.
0 subscribers moved to trash – the message appears when tried to delete
before the update i deleted the subscribers successfully
there are no errors in developer console in chrome or in server logs
Have you imported the users in the past? Then possibly the userno contains the value ‘0’. Mailpoet does not delete a record with userno ‘0’. That is a problem I already reported.
Can you check this value ?
Ok then you cannot delete them via mailpoet.
But if they became wordpress users, that is very strange.
Mailpoet normally does not add subscribers to wp.
No, I meant they became wp users in wp_mailpoet_subscribers table (is_woocommerce_user changed from 0 to 1 for most subscribers but not all – 27 of 411 were not changed). Actually there are 237 wp users on my website, all others subscribed via form.
Very strange issue…
Ok that explains the fact that you cannot delete them. It appears to me that for some reason the boolean for subscribing has been put into wrong field if all these subscribers became user 1
Does user “1” exist in wp as a normal user?
To be able to delete the subscriber, the userno should be empty e.g. no value in the field userno
Do you use WooCommerce? If so, it appears the existing values are being updated to the fact that the user is a WooCommerce guest (value 1) preventing the delete. Can you please confirm?
