When logged in users go to create a new post in the "Courses" post type (all of which is setup in Toolset, and which has worked fine in the past) they instead see an error.
I have also provided the full error text that appears on the page, as follows:
remove code as per user request
Please can I have help urgently, as members are trying to add courses today and not able to do so.
Hello. Thank you for contacting the Toolset support.
After checking to debug the information you shared with us, I found that you are using an outdated WordPress version. We always recommend running your site with the latest stable release software version.
Can you please update the WordPress to the latest 5.3.2 version and check if that helps you to resolve your issue.
