When I install MySQLoo on my server, it messes it up.

Like how, what are the errors?

Those are some REALLY helpful and descriptive information you have provided.

Sorry for my vague description, when I install it onto my VPS it breaks any gamemode I run.

Again, comments like “it doesn’t work” and “it breaks the game” is not helpful at all.

Be more descriptive on how it breaks the gamemodes, like how is the game different from before and after. We can’t read your mind.

What gamemode are you running?
