If you have troubles since the update to WordPress 4.5 please read this post before opening a new thread.
when using ECPT (Easy Content Types 2.4.2) by pippinsplugins.com (which activates featured images) I can’t add any media into posts or pages using latest Velvet theme and WP.
Fatal error: Call to undefined function get_post_thumbnail_id() in /home/.sites/393/site483/web/gambrinus/wp-admin/includes/media.php on line 1173
How can I fix this?
which version of Velvet are you using? Since version 1.1.2 Velvet sets the first slideshow image as “post thumbnail aka featured image”. Try to update to the latest version (1.1.4) and see if this solves the issue.
Using latest velvet (1.1.4) but can’t add any images into the post.
After image has been uploaded the error message
“Fatal error: Call to undefined function get_post_thumbnail_id() in /home/.sites/393/site483/web/gambrinus/wp-admin/includes/media.php on line 1173”
appears in the layover window of the mediathek.
any news on this issue – the theme has a buggy featured image implementation I think…
