Does not seem to work in Moodle 3.11. I get the following error in the php error logs:

Is there a way to automate this? That all new courses get a default template no matter how they get created--manually or with a course feed?

I am trying to enable access to the plugin for one of our roles. I enabled the following permissions: course template view, backup courses, backup user data, restore courses, restore user data, approve course creation. I am now getting an "error/setting_locked_by_permission". Any ideas why this is happening?
Moodle 4.0.2

@Zak
I had a the same "setting_locked_by_permission" error trying to enable templates for course creators. Assigning "moodle/restore:configure" and "moodle/backup:configure" capabilities did the trick for me.

Thanks a lot, @Blaukraut Suppe! The backup:configure actually solved the problem.

@Zak Stoimenov @Blaukraut Suppe
I allowed for following capabilities
Allow: local/course_templates:view
Allow: moodle/backup:backupcourse
Allow: moodle/backup:userinfo
Allow: moodle/restore:restorecourse
Allow: moodle/restore:userinfo
Allow: moodle/course:create
Allow: moodle/site:approvecourse
Allow: moodle/restore:configure

On the third step "Define Settings" of Create a course from a template, I am getting the error, "Course or activity not accessible." after the user click continue after entering Course name & Course short name.
Moodle 4.0.1

Can you please hint, what I might be missing?

@Vipin Saxena, I got the same message but figured that it is because my template course is hidden. Check to see if that's your case as well. Simply unhide it and the error should go away. I hope this helps!

@Vipin Saxena
Zak's tip sounds good. If that doesn't help, try assigning "moodle/course:viewhiddencourses" or even "moodle/course:view" permissions. (course:view allows users to see content of courses they are not enrolled in. Only use that if appropriate for the role you are assigning to.)

Does not seem to work on 3.9.16 (at least on my installation), keeps throwing an error that the course category doesn't exist in the DB. I beg to differ, after checking I can see the category and course in the "non-existent table". Spent a couple of hours on it and never got it to function.

Hi, I was wondering if this will be available in Moodle 4.0 please? Or are there any alternatives?

Hi,
First I would like to thank you for your great plugin,
I used it in my university, and I have a manager for each college, and I want each manager to be able to restore only one template. to do this I didn't give any of them permission in the course templates category, but I enrolled each one of them as a manager in his template. this works great for me where when any admin tries to use a template not belong to his college he will get a message you don't have permission to do that.

THE ONLY ISSUE REMAINING IS

The admin is enrolled in all newly created courses, is there a way to have a setting to prevent user enrollment to be included in newly created courses from the template?

Hello, first of all, thank you for this plugin.
Have you planned to update the software for compatibility with Moodle version 4.1.1?

@Keith VW
This error occurs when there is no category id 1 on the site, which is the one that the plugin sets by default. It is a bug.
You can try to access with the address by sending an id of an existing category, no matter which one, so that it does not use the default one, example: www.yoursite.com/local/course_templates/index.php?cateid=6

I want to express my gratitude for the excellent plugin you've provided. While using it, I designed a course template with the Course visibility option set to "hide." Additionally, in Moodle settings, the course defaults also have Course visibility set to "hide." However, when I use the template to create a course, the course is generated with the Course visibility set to "show."

I have another query: Is there a method to enable users to create courses from templates without granting them the ability to create or restore courses in any other way? I aim to restrict course creators to exclusively using templates for course creation, disallowing other methods.

it shows the following error:
