Hello. Thank you for contacting the Toolset support.
Can you please make sure that the shortcode "count_post_terms " is registered at:
=> Toolset => Settings => Front-end Content tab => Third-party shortcode arguments
If the shortcode is already registered then I will require to debug and you will require to share information where you added the shortcode on what page/post, the link of problem URL and access details.
*** Please make a FULL BACKUP of your database and website.***
I would also eventually need to request temporary access (WP-Admin and FTP) to your site. Preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed.
I have set the next reply to private which means only you and I have access to it.
