The plugins are out of sync
What does it mean when The plugins are out of sync?
When you have installed Level Up XP+, and later on upgraded Level Up XP, the plugins fall out of sync. This means that Level Up XP+ is now extending a version of Level Up XP that it was not developed against.
warning
We strongly advise against upgrading a plugin without its counter part to ensure the integrity and the well functioning of the plugins.
warning
When a version of XP+ becomes excessively older than that of XP, XP+ may automatically disable itself to prevent malfunctioning.
