[Server] Problems loading plugins in ubuntu

[McZulian]

Hi! I'm McZulian (sorry if my english is kinda bad, i'm argentinean)
I'm trying to create a SAMP plugin using an ubuntu VPS becouse the gamehost forced me to use MySQL R41 and my gamemode uses R39 and i can't update it.
I did everything, i have an ftp connection to the server, phpmyadmin running well and everything. But when i try to run the server, it runs, but my gamemode does not work. And it does not load any of the plugins i have.
This is my server log

i'm using South Central as a base gamemode

I did everything in my knowledge and still didn't get it to work. In my pc, using windows it works just fine, no problems there. But when i go to a linux server, everything goes to hell

Did you add ".so" to them in server.cfg?

Code:

plugins sscanf.so mysql.so streamer.so whirlpool.so nativechecker.so

You didn't add ".so" after the plugins.
