Hi Moshtafizur,
unfortunately I have checked today and the issue still persists, we cannot edit or save some product details. I have had to switch off the EAN plugin, which is not ideal. I have emailed you the logins already, but also, you are free to look at the staging site, where you will also see the problem with the plugin enabled. https://staging9.theenglishsoapcompany.trade/wp-admin/
If you enter your email address you can reset your password.
Thanks
Lucy
