Not showing messages properly

Hello, 

From one month ago I never get any wipe announcements on my discord but if I use the dw wipe command it shows.

The problem is the placeholders are not working , can you help? Im new to this tho. 

Just shows the placeholder code.. what do I have to do?

🚨 SERVER JUST WIPED 🚨
Size
{world.size}
Protocol
{server.protocol.network}
Click & Connect
{server.address}steam://connect/*.*.*.*:{server.port}
BluePrints
{server.blueprints.wipe.last:MM/dd/yy hh:mm:ss tt!local}
{server.name}
 

Fixed, Just updated the plugin PlaceholderAPI. The thing is that im using UpdateChecker and it didnt show there was an update.
