I am running a Drupal 6 site using the SMTP (6.x-1.0-beta5) and the PHPMailer (6.x-2.2) modules for messaging. I configured SMTP and PHP messages, successfully sent and received test messages.
I am using the Organic Groups module and trying to utilize the messaging functions in it, for example receiving notifications for administrator users regarding membership approval.
Drupal isn't sending any mail. When I checked the recent log entries, it reports this error.
Could not locate PHPMailer library
In /admin/messaging/settings I use HTML Mail (PHPMailer) as the default sending method.
Please help me to resolve this issue.
