i already did the o.grant user cryo playeradministration.access.show in the server and it says i have perms but in game it doesnt i dont, iv tried rejoing the server, retarting my game ad restarting the server its self but nothing is working

I would suggest if you are admin you use this instead

oxide.grant user <user_name or STEAM64_ID> playeradministration.*

Worked for me
