AlliedModders - Other plugins doesn't find SteamTools

Code:

Looks like it doesn't find SteamTools.

I have the steamtools.ext.so in my extension folder, is there anything I have to do to active it or do I also need something else?

Thanks!

EDIT:

Solved it by refreshing everything and restarting the server.
