Having trouble with permissions

Hi
I am new to Rust, and even newer to server ownership and mods.

I have set my server up,and installed a few plugins,namely Adminpanel,gather rate,stack size backpack....bla bla bla
Went into my server and info panel works ok, but admin panel or the other mods arent?
I have tried every variant of oxide.grant.....  and it simply returns what i have asked below,with no action.
I understand i am owner then i should automatically have oxide admin?

Most of the mods in CFG are near empty or give me no option to add myself or give myself permissions!

Sorry, i know i am a noob,but i am bleeding money everyday for a server i can use,but not how i would like to use it and with the mods i would prefer to use.

Any help would be amazing.
Thank you.

We would need to know how exacatly you are trying to give yourself permissions for those plugins. Being "admin" doesn't automatically give you any plugin permissions. If the command replies you use show how to use it, you aren't using them right.

Thanks for the reply Wulf.

I have installed info pan/admin panel/gather manager and stack size controler.
NONE of them work?
I have installed them in my server folder (rented server now) and restarted the server,but nothing?
I tried oxide.grant ............permission, just responds with same command,not in a different colour to show it worked.
I know some plugins/mods? work just by being installed on the server without any permissions,but none are working now.

As i said, i am a noob. i have tried everything i can imagine before comming here to bother you busy people.  But i now am at the stage of just quitting Rust all together.
I just want to run a server,that has a few decent mods for the players to enjoy,and be ablt to control it with admin panel!
Any help would be great.
Thank you in advance.
