Hi Tom,
I am using your last php code to disable post navigation.
I noticed that in all my site’s posts this tool http://www.seoreviewtools.com/html-headings-checker/ find an h6.
It say:
H6: Post navigation
I tried other similar tools and I had the same result, they find the “H6: Post navigation” in all the posts of my blog jobseekeritalia.
I don’t find this “post navigation” txt in my posts.
Do you have any idea of the cause of this problem?
Thanks a lot
