- Plesk Onyx 17.5 for Linux
After a restoration of backup for domain example.com with additional dedicated IP address this domain is set as "default domain" for a shared IP address.
The "default domain" was not set Plesk before backup restoration/migration.
A bug with ID #PPPM-6920 which will be fixed in one of the next product updates.
As a workaround perform the following:
1. Log into Plesk interface.
2. Set "default domain" option for affected IP address under Plesk > Tools & Settings > IP addresses to "none" after backup restoration/migration.
