- Plesk Onyx for Linux
Note: This article has the reference to the issue with the fix available:
- #PPPM-8034 "Support issue #PPPM-8034"
- Plesk Onyx 17.8 Release 17 April 2018
At Plesk > Extensions the Developer Pack is required to be purchased even if the licence is Web Pro or Web Host edition.
It is Plesk bug PPPM-8034 which will be fixed in future Plesk versions.
This error does not affect anything because the Developer Pack is already included in Web Pro or Web Host edition licenses.
It can be safely ignored.
