- #PPP-28433 "The mchk utility reset the ‘Certificate for securing mail’ setting to the default value."
- #PPPM-5725 "Support issue #PPPM-5725"
Upon an attempt to set mail server certificate via Tools & Settings > SSL/TLS certificates, the following error is displayed:
PLESK_ERROR: Error: sslmng failed: ERROR:failed to configure qmail service: ("Unable to configure SSL certificate '%s'", AttributeError("'module' object has no attribute 'shown'",))
The following attempt to apply the certificate is successful.
QMail mail server is used.
Plesk bug #PPPM-5725 which will be fixed in future product updates.
Until the fix became available, reapply the same certificate one more time.
