Email Sending Failed - Email Sending Failed: Call to undefined function WHMCS\Module\logAdminActivity() (Subject: Invoice Payment Reminder)

[AlexNgian]

I am getting this error even after uploading the hotfix here 

 

This seems to occur only for reminder email sent during automated task. 

Anybody facing the same issue? Any solution?

Do you have any hooks using the logAdminActivity function?

Thanks for your reply.

No. I don't have any hooks using logadminactivity function.

It seems like the failed reminder attempt also deleted the invoice that the reminder was meant for.

I don't know what else to do. Probably will have to reconfigure the SMTP portion. Will have to stop processing my invoices on WHMCS if it is randomly missing.
