I've been trying to get access key to moodle messaging server. However, I'm getting an error saying "An error occurred while retrieving key. Your Moodle site must be registered with Moodle.org to use this service. You may need to re-register to update your details there". I've registered my moodle page 5 times and I'm still getting this error. I have 2.7 version of moodle.
Can anybody help me with this?
