Solution:
It seems you must have created a content template before for the post type "Free Items" and didnt provide the proper name for that CT then deleted it and then created a new CT and assign it. Due to that there must be some edge case and the new CT was not assigned properly.
Problem: I'm using the WP Mail SMTP plugin to send SMTP emails. When I use the Forms Test Email feature, I receive an AJAX error 500 with the error log text as follows:
PHP Fatal error: Cannot declare class PHPMailer\PHPMailer\SMTP, because the name is already in use in /path/to/site/wp-includes/PHPMailer/SMTP.php on line 30
Solution: In this case, another SMTP plugin provided an error-free solution. It appears to be a problem in the WP Mail SMTP plugin itself, as other errors are reported for the same plugin on third-party support forums.
The issue here is that the user wanted to know if they needed a site key for their staging site as well.
Solution:
No you do not need to register your staging site as you can still update your Toolset plugins manually. Our Toolset plugins will still continue to function normally even without a key.
We document known issues and their solutions in Toolset errata. Save time by checking there first and seeing if what you are facing is a known issue. This list is kept short. We do our best to resolve all known issues with every release of Toolset plugins.
