- Plesk 12.0 for Linux
Plesk does not restore custom buttons, only one button which was added first is restored and others disappear.
For example, initially there were 2 custom buttons
After restoration full-server backup which is supposed to contain these custom buttons, only the 1st button
This behavior has been confirmed as a software issue with id #PPPM-2428 , the fix will be included in future product updates.
