Hi, I want to know whether installing an addon is a completely reversible process in xenforo system irrespective of the addon? I mean if I install any addon, is there a chance that it will change my original xenforo system to some way that I can't revert it even by uninstalling that addon? The question I am asking because I am planning to install some beta version (like xfarcade and some other addon as well) addons. But little bit anxious to do so on my live forum. Appreciate any advice and apology if the question sounds very lame (i have no idea how xenforo works ).
