ClearFX is a (very) lightweight plugin to allow administrators to clear players' potion effects. It is useful to force players using invisibility potions to become visible, or to remove speed/strength effects being used to cheat in PvP arenas.
Commands
/clearfx - Clears your own effects
/clearfx <player> - Clears another player's effects
Permissions
clearfx.clear - Gives access to the /clearfx command
clearfx.clear.self - Gives access to clear own effects
clearfx.clear.others - Gives access to clear other players' effects
Note that both clearfx.clear and clearfx.clear.self are needed to be able to clear your own effects; likewise, clearfx.clear and clearfx.clear.others are needed to clear others' effects.
Configuration
No configuration is needed for this plugin.
Source code
The plugin's source code can be found on its GitHub repository.
