Problem/Bug PEX No Such Method Error

Hi guys and girls,
I got an error while enabling PEX.
I Use PermissionsEX 1.23.3 and Spigot 1.8.8 R0.1. WEPIF is used, permissions.yml from bukkit is empty and permissionsex is connected with mysql for a bungee-cord-system. It doesn't work only on one server, configs are same also the permissions.yml (both) and the wepif
Error:
java.lang.NoSuchMethodError: com.google.common.cache.CacheBuilder.maximumSize(I)Lcom/google/common/cache/CacheBuilder;
