No help for me… Too bad 🙁
Thank you for answering.
But yes, of course “Allow comments on this post” is checked in that post.
I’m afraid the problem is a bit more hidden, but have no idea of how to find it.
Any other idea?
Thanks.
The same issue has happened to me some times. When I edit a plugin (or any other php file) from the file manager that comes with cpanel, it adds empty lines at the end of the file (after ?>).
TO SOLVE THIS you only have to delete those empty lines.
