I had my plugins and everything working about 3hrs ago then all the sudden nouthing loot stops being multiplied same with mats and when I type a command like o.reload BetterLoot nouthing happens and no console commands on rust admin app are working either 

try *ingame opening console (F1) and type plugins to see what ones are running. 

If native Oxide commands do not work and show as "Unknown command" or not at all, and plugins do not work, it's likely you do not have Oxide installed.

Mine arent working either.
Just updated the server and my steam game and now whan I type in a grant command nothing happens.
No error, no message, just nothing happens.
I checked the server FTP and Oxide is still installed and so are the plugins.

One of the plugins is working, Authentication, where you have to enter a password before times up and you get booter from the server.
The others are not showing, Backpacks, QuickSort, Boxsorterlite, or Simplesort.
