Hello. Thank you for contacting the Toolset support.
Toolset Layouts plugin is in maintenance mode. If you have not many layouts build then we suggest instead of using Layouts plugin, you should use the Toolset Blocks/Views plugin to build the content template for your single post. But before performing any action:
*** Please make a FULL BACKUP of your database and website.***
If you still want to use the Layouts plugin and do not want to migreate to Toolset Views/Blocks then I will require debug information.
