Hi my issue seems to be with the crontab entry, not the Content Notification component itself. When I added the crontab entry as documented (replacing the URL and password with my own), and I added a MAILTO to the crontab entry, when it ran, the following appeared at the top of the email I received:
/dev/null: Scheme missing.
I found Ticket #2331 mentioned the following documentation error:
Instead of writing: "wget -O --max-redirect=10000 /dev/null "http://etc." you should write : "wget -O /dev/null --max-redirect=10000 "http://etc."
So, I changed the crontab entries like this:
*/30 * * * * wget -O /dev/null --max-redirect=10000 "https://mysitename/sitefolder/index.php?option=com_contentnotifications&task=notifications.createUpdates&password=mypassword"
But, it still doesn't quite seem to work. That is, I have a bunch of updates in the Updates list, but no emails in the email queue after the createEmailQueue entry runs.
Is there something else I need to change in the crontab entry that you can see in my example above?
Thanks for the help.
