Hud not working error code

receive error code on grid Nirvanna when tyring to use Hud

02:35] OSSL Runtime Error: osSetDynamicTextureDataBlendFace permission denied. Script creator is not in the list of users allowed to execute this function and prim owner also has no permission.(script: oscheck event: timer primID:6d28310f-169d-4c56-9648-8e716002aada at <67.60165, 124.9249, 28.79674>)

the region owner is ok other members on same region can not. Admin does not know how to fix it.

If not done already, change the following lines in osslEnable.ini

[NOTE: in opensim ini files the  ;  symbol at the start of a line turns it into a comment. In the following, we comment out the first two lines and uncomment the next two]
  osslParcelO = ""
  osslParcelOG = ""
  ;osslParcelO = "PARCEL_OWNER,"
  ;osslParcelOG = "PARCEL_GROUP_MEMBER,PARCEL_OWNER,"
TO
  ; osslParcelO = ""
  ; osslParcelOG = ""
  osslParcelO = "PARCEL_OWNER,"
  osslParcelOG = "PARCEL_GROUP_MEMBER,PARCEL_OWNER,"
 
Then edit the following to allow members of the parcel group to use this function...

; ThreatLevel  VeryLow
Allow_osSetDynamicTextureDataBlendFace = ${OSSL|osslParcelOG}ESTATE_MANAGER,ESTATE_OWNER

grid owner in Nirvana installed the codes you recommended but still get this message

Are you sure that the Parcel group is the same as the group users set when there (i.e. the user and hence the HUD are same group as the parcel)?
