Hi Amanda
The most likely cause of the persistent 'not registered' message, is that the URL you registered does not match the URL of your Moodle site . Commonly one or the other has a 'www' and the other does not. Also note that the registered URL should start with 'http' or 'https'
GOOD
| Registered URL | Moodle URL |
|---|---|
| http://mysite.com | http://mysite.com |
| http://www.mysite.com | http://www.mysite.com |
BAD
| Registered URL | Moodle URL |
|---|---|
| mysite.com | http://mysite.com |
| http://www.mysite.com | http://mysite.com |
If you still can not fix it, then visit your site's support info page:
Site admin -> plugins -> filters -> poodll -> Poodll support information
and export the information there (using the export button) to a csv file.
Then send it me via https://poodll.com/support
