Signup Enrolment Plugin Error

Hey Joomdle folks,

I want to first thank the developers for creating this component. It has been a tremendous time-saver and it works well.

I'm not sure if this is the place to post my question, but I didn't see an area for the extra plugins on the forums, so here goes.

Some months back, I installed the Signup enrolment plugin. After a little struggle getting it set up (Which was my fault), I enabled it on a course, added 40-something users and it worked perfectly. This morning needed to enable this enrolment method in a different class and enter a bunch more users.

So I disabled the enrolment method in my first course, cause I don't want them enrolled in that course, and added it to my new course. I added a student and got an XML-RPC error:

Coding error detected, it must be fixed by a programmer: invalid enrol instance!

So I deleted the Signup plugin on the second course and tried again and got the same error. I re-enabled it on the first course and added a new user with no error.

I'm on Joomdle .82
Joomla 2.5.4
Moodle 1.9
PHP 5.3

Any help would be appreciated.

Sorry to state the obvious but if only the courses / classes have changed there is likely to be some configuration option / setting that is different. It ma not be so obvious from the browser and perhaps you need to compare in the database?

I don't think it's a configuration issue. The plugin works fine when it is enabled on both course, or other courses even. But if I disable the plugin in any of the courses it is enabled in (Not delete it, just disable it) Moodle throws an error when I register a new user.

Edit
I think line 77 of lib.php in the signup plugin throws the error.

Thanks for the bug report. I will try to find out what is wrong next week (no time this one), and let you know.

Thanks Antonio.

Hi.

I have made a change, and it seems it solves the problem. If you want to try it, please drop me an email at antonio@joomdle.com and I will send it to you.
