Hello , I have a problem with this plugin . I've installed PreciousStones and made my config in my language , deleted all the stones but the Anti-PvP one and the Protection one , Made a Big Protection stone and then it all worked fine for two months. But in the 3rd month I saw that the plugin didn't work anymore , neither the config and even if I redownloaded my version for Spigot 1.8.8 and as soon as I install the config it doesn't work . If you are wondering about the error it says Command Not Recognized , even when I type /ps , /ps help and etc. How can I solve my issue ?
