Why do I want to hide an error. Well I made this plugin for one of my modded servers, one of the mods in the modpack was spamming the console very bad, and since I could not update the modpack myself to fix the problem I had to do something because the error become so spammy that the logs were 5GB in size also because of this intense spam the server was freezing sometimes and crash. Hiding that error that was not affecting the game in any way except the spam issue, reduced the logs to a normal size and also kept them readable. Without that mad spam the server is stable now. This is an example of why I needed this plugin. I just decided to post it here maybe someone else will need it too.

Indeed logging them to a log may be a solution, I'l think of that maybe on a future update, but that will need to make sure the log will not get in crazy large size.

Also note that this plugin only hides errors that you configure to be hidden, by default will not hide anything. So this will not hide all errors, but only the ones you want to.

Since it hides the errors that you configure the plugin to hide, I assume that you know what error you hidden, so i'm not sure why you need them logged in a separate file.
