Well, seems obvious, that when sales are set no "no", in settings, no need to activate and/or enter data in payment methods.
After deactivating sales, and deactivating all payment methods, I have get this message:
Notice: Undefined index: eshop_method in /home/kkkkk/public_html/beta/wp-content/plugins/eshop/eshop-settings-extends.php on line 1376 Warning: Cannot modify header information - headers already sent by (output started at /home/kkkkk/public_html/beta/wp-content/plugins/eshop/eshop-settings-extends.php:1376) in /home/herbacen/public_html/beta/wp-includes/pluggable.php on line 890
Hope to be helpful. Thank you.
