i have tryed to install Vault on my minecraft server. everything is setup. and i have plugins i need that also need the plugin vault. it tells me that it can not find the file in plugins. in my files. i look there and there is nothing with vault. what should i do?

Vault doesn't install anything extra. simply having the plugin is all you need. I'm not sure what you mean it's saying it can not find the file? To further help you I would need some log files of the actual errors you're receiving.

Closing this issue. If you have a log or a more extensive report please post the info and I will look at it. it does sound like you're not sure what Vault is for though, and are looking for the wrong plugin configuration.
