Hi fokhrulabedin,
since we have already provided the solution to hide author name, so while hiding that element the separator icon, so to show the separator icon either you have customize the code to remove code for author name or in your case we can do it custom CSS code. but if add code while the author name is shown as default then the comment meta will have 2 separator icon.
anyways please go to the ‘Appearance > Customize > Additional CSS’ and paste the below custom CSS code.
.entry-meta > div:after,
.entry-meta .comments:before {
content: "|";
}
Thanks
