I think it’s because you didn’t add a title to the post. Try adding a title.
I don’t want it to have a title either.
If you do not want it to have a title, you would have to manually hide the title using some CSS. I would need the link to that post so I can give you the exact CSS to use.
The image above says that the post ID is 38, so you can add this CSS by going to Appearance → Customize → Advanced Settings and copying & pasting this rule in the Custom CSS field:
.post-38 .entry-title {
display: none;
}
The custom CSS did not remove the post ID.
I have identified the source code as;
<h3 class="page-title">Post ID: 38</h3>
I have tried the following variations and none remove the Post ID:38;
.page-id-38 .page-title {
display: none;
}
#post-38 .page-title {
display: none;
}
.page-id-38 .entry-title {
display: none;
}
#post-38 .entry-title {
display: none;
}
.post-id-38 .page-title {
display: none;
}
.post-38 .page-title {
display: none;
}
Does this line have anything to do with it?
<div class="clearfix post-38 page type-page status-publish hentry" id="page-38">
I have noticed that “hentry” is probably supposed to be “entry”
SOLVED
The code was;
.page-id-38 .page-title {
display: none;
}
It turns out that I had to use the Customize > Additional CSS area to make these modifications.
The Customize > Advanced Settings > Custom CSS did not work.
Glad you were able to resolve this. Best of luck for the future!
