Can someone fix this factions problem
I have a 1.8.7 server and I am using V1.6.9.5
There is a error in the log

Can someone fix this please?

 

Form what I can read you bukkit is to old, but I think your factions is to old . It should be fixed by using an newer version of factions and massive core. Here are the download links for old versions of the plugins. Please make sure you are using compatible versions of Mcore and factions.

Factions Or http://dev.bukkit.org/bukkit-plugins/factions/files/

Massivecore Or http://dev.bukkit.org/bukkit-plugins/mcore/files/

 

I fixed the problem - I needed to use a older version of bukkit

 

Or you can update your factions.
