When i try to grant the players of the server permission to get raidblocked etc. i use this in RCON 

oxide.grant group default noescape.raid.tpblock
But the respons is the following

Permission 'noescape.raid.tpblock' doesn't exist
What do i do wrong? and is there a more easy way to get all permission given to players at once

Generally when you see that a permission "doesn't exist", it is either typoed or the plugin that registers it isn't loaded.

And what is my options to correct this? i cant find a souloution to the problem

Have you verified that the plugin is loaded and that there are no errors related to it in your oxide/logs ?

Hello Wulf, first i want to thank you for your VERY swift respons! 
I have been up the last 2 nights trying to wrap my head around these server files. 
To answer your questions, i have just downloaded the files direclty from the UMod section and uploaded in my plugins section under oxid. The error msg still comes up Permission 'noescape.raid.tpblock' doesn't exist.

In the server logs u refferd too, is this the only thing shown about NoEscape 
NoEscape.cs(55,15): warning CS0649: Field `Oxide.Plugins.NoEscape.combatOnTakeDamageMinDamage' is never assigned to, and will always have its default value `0'
NoEscape.cs(193,22): warning CS0414: The private field `Oxide.Plugins.NoEscape._htmlRegex' is assigned but its value is never used
NoEscape.cs(1112,17): warning CS0219: The variable `targetMembers' is assigned but its value is never used
NoEscape.cs(1996,32): warning CS0168: The variable `ex' is declared but never used
NoEscape.cs(2010,32): warning CS0168: The variable `ex' is declared but never used
NoEscape.cs(2024,32): warning CS0168: The variable `ex' is declared but never used

again, thank you for your time!

Wrong log, that's just the compiler log and warnings. You can check your normal oxide/log to verify if it is loaded or not and test with the commands that the plugin provides. Since you are having it with multiple plugins though, sounds like the plugins aren't actually loaded.
