Problem mod_customcert\task\email_certificate_task not send email

[MaurizioBelli]

My Moodle is unable to send certificates via email and returns the following problem:

Execute scheduled task: Gestisce l'invio dei certificati via email (mod_customcert\task\email_certificate_task) ... started 02:05:01. Current memory use 19.9 MB.

Can you help me? How can I solve it?

Looks like there is a bug in Moodle or something strange going on with your Moodle site. Do you have any customisations? The error is coming from get_enrolled_users() which the certificate calls but it fails before it gets a result back which to me seems this is not an issue with the plugin. This will require someone debugging your code and seeing what they can do.
