i can't figure out what it means and what would help.

 

update plugin

 

update the signshop plugin?..

 

yes..?

 

just tried for the third time.. still same error

The main problem i think is; "could not pass event PlayerInteractEvent" to signshop v2.5.1.dev
after one other reinstall where vault and signshop is the only plugin with a fresh install of bukkit, and java it still doesn't want to work probberly ...

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

thats not the latest build.

 

its the one that matches the bukkit build. thought that would matter


replaces it with newest build, new vault build also,, still nothing..
maybe its that ::
[WARNING] [SignShop] Could not hook into Vault's Economy!

Please update to the SignShop 2.5.2 and make sure you have an economy plugin installed. Vault itself isn't an Economy plugin. Examples are BOSEconomy, Essentials Econ, etc.
And if you have any further questions please post them here: http://dev.bukkit.org/server-mods/signshop/

 

still doesn't work. done with this,, got chestshop wirking instead.
