I know this has been asked many times. But im telling you, I am a competent programmer, and have tried EVERYTHING. I have gone through this entire community form looking for answers. And nothing has fixed this. So please, any help is greatly appreciated.
So naturally, I install the plug in, it generates its config.json file, I go into it, its just an empty object of an array. Now I have literally copied line for line, what others have said is successful for them. I have even went as far as removing all white spaces, having only the item name, the "Comma" then next item name, etc. Still didnt work. Here is my BlueprintManager.json:

{
	"Settings": {
		"Default blueprints": [
			"barricade.woodwire",
			"wall.frame.fence",
			"wall.frame.fence.gate",
			"rug.bear",
			"spikes.floor",
			"table",
			"floor.grill",
			"water.catcher.large",
			"wall.frame.garagedoor",
			"watchtower.wood",
			"water.catcher.small",
			"barricade.sandbags",
			"barricade.stone",
			"fireplace.stone",
			"gates.external.high",
			"wall.external.high.",
			"shutter.metal.embrasure",

I as well, under my oxide/server_identity/cfg/server.cfg have: 
blueprintmanager.config

To run and give all users said blueprints that are in said config.json file. But no matter what I do. No level 1's are unlocked... 

Any help is greatly appreciated, thanks.

blueprintmanager.config is a permission, not a command. See https://umod.org/documentation/plugins/permissions for information on permissions.

AH! My favorite! WULF DUDE! Your like a celeberty around here! I remember you helping me back when uMod didnt exist, and it was just regular oxide forums. Glad to see you man! So please forgive me for not understanding. But looking through this link you provided, I see how I can add individuals, or groups. But how do I set this permission for everyone who joins the server? Sorry to ask you to hold my hand... But ive honestly been tinkering with this for days... Coudl you possibly just shoot me an example command? Thanks WULF! ;)

Something Like,

oxide.grant ALL BlueprintManager   ????

oxide.grant group default blueprintmanager.config

Thanks as always Wulf! however... It unfortunately still doesnt work... I added this to my server.cfg oxide.grant group default blueprintmanager.config
and reloaded the plugin, but nothing happened once again... Do I need to restart the entire server?

The command only needs to be ran once, via RCON., local server console, or your F1 console (as owner). The player would likely need to reconnect to get the blueprints unlocked.

omg... I see... So what Im confused about... Is when I put that command in my server.cfg, it is automatically run via rcon on startup. So how is it when I have oxide.grant group default blueprintmanager.config in my server.cfg, it doesnt hit? Also, does that mean I need to do this oxide command every time server restarts? Thanks agwain Wulf! 

Edit: I just typed this command in rcon and left, rejoined. Still didnt work....

Typed it again:
Group 'default' already has permission 'blueprintmanager.config

Merged post

Dang it I tried to edit but I waited to long.. I appologize.. Not sure why it didnt work the first time, but I left the server again, and re-joined. This time all level 1's unlocked. Thanks man! And sorry for my user error...

Also, on the last item in the list, you have a full stop.

"explosive.satchel."​

The last item in the list should be : "explosive.satchel"​

Your right man, it was that typo which I thnk was throwing everything off. As soon as I removed satchel and bean can(as I never wanted that) it worked perfectly. Thanks guys!
