Why isnt MVdWPlaceholderAPI working?

Hey,

The MVdWPlaceholderAPI is in my softdepends, server, and it checks if the plugin is on before executing anything on it.

Code (Text):

if (Bukkit.getPluginManager().isPluginEnabled("MVdWPlaceholderAPI")) {
                        for (String str : toSay) {
                            str = PlaceholderAPI.replacePlaceholders(e.getPlayer(), str);
                            e.getPlayer().sendMessage(ct.cc(str));
                        }
                    } else {
                        for (String str : toSay) {
                            e.getPlayer().sendMessage(ct.cc(str));
                        }
                    }

Output:

Code (Text):

[19:03:29 INFO]: InstantlyMoist issued server command: /dis
[19:03:29 ERROR]: [MVdWPlaceholderAPI] Unable to replace placeholders. No MVdW Placeholder plugin found!
[19:03:29 ERROR]: [MVdWPlaceholderAPI] Unable to replace placeholders. No MVdW Placeholder plugin found!

Discord command:

Code (Text):

discord:
  message:
  - '&a&lJoin our discord now!'
  - '&a&lLink: blabla.com {issneaking}'
  permissionNode: NONE
  aliases:
  - dis

 

So just the MVdWPlaceholderAPI plugin isn't good enough? What do I need then?
