Hi there,
Thanks for writing in! You can hide the featured image on any post using it’s post ID e.g try adding the following code in the Theme Options > CSS:
.postid-1510 .entry-featured {
display: none;
}
To find out Post ID’s please see https://theme.co/apex/forum/t/setup-how-to-locate-post-ids/59 you can then replace postid-1510
with actual Post ID in the above code.
