Hello. Thank you for contacting the Toolset support.
Well - I need to check on your install why single post content template is not working on your install. Could you please share problem URL on which you want to apply content template and which content template you would like to apply.
*** 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 would additionally need your permission to de- and re-activate Plugins and the Theme, and to change configurations on the site. This is also a reason the backup is really important. If you agree to this, please use the form fields I have enabled below to provide temporary access details (wp-admin and FTP).
I have set the next reply to private which means only you and I have access to it.
Could you please check now, I can see the attached content template now displaying the content.
=> hidden link
The issue was the theme you were using not using the standard the_content() function to display the content so you need to register the function which is responsible to display the content at section:
=> Toolset => Settings => Front-end Content => Theme support for Content Templates
