Dear Sir/Madam,
I installed all the latest versions of Toolset plugins and the theme is GeneratePressVersion: 3.1.3, I create a content template for a custom post Book, I disable the Featured Image but it doesn't work.
I grant the site access. You can access the Content Template from hidden link
From the content, there is no featured image but I can see the image from hidden link
<center>[types field='book-cname'][/types]<br/>
[types field='book-ename'][/types]<br/>
by [types field='book-author'][/types]<br/>
[wpv-conditional if="( $(wpcf-book-audio) ne '' )"]<a href="/player.php?media=[types field='book-audio'][/types]&title=[types field='book-cname'][/types]">Audio</a><br/>[/wpv-conditional]
[wpv-conditional if="( $(wpcf-book-pdf) ne '' )"]<a target="_blank" href="/doc/[types field='book-pdf'][/types]" rel="noopener">PDF</a><br/>[/wpv-conditional]
[wpv-conditional if="( $(wpcf-book-ppt) ne '' )"]<a target="_blank" href="[types field='book-ppt' output='raw'][/types]" rel="noopener"></a><br/>[/wpv-conditional]
My issue is resolved now. Thank you!
