I've used ShopGUI+ and Vault before, and I recently restarted on my server. Whenever I log into the server, Vault is enabled but ShopGUI+ is not. I reinstalled the files several times, removed all plugins and retried, and it still did not work. I also tried to use the free ShopGUI which still didn't work. I went into the console and found that it said, "Vault could not detect an economy plugin!" 99.9% sure that both Vault and Shop GUI+ are installed correctly, but it just can't detect it. If anyone has experienced this issue and have a solution, please let me know. (I originially had PEX and LuckPerms installed, still did not work.
