I have uninstall the faction for 1.8. I install the final version. When i trie /plugins i see Faction plugins. But no features of this plugins.

The Server log of faction 1.8 Does not display the word faction.

But the server log of Faction final (1.12) say :

[16:00:00] [Server thread/INFO]: [Factions] Enabling Factions v2.11.0

Essayez de faire vos factions plugin dans la version inférieure non dans le dernier.

Bonjour, j'ai essayé la première version de Factions et rien. Lorsque / plugins, faction appers pas.

Le journal du serveur de Factions:
