ive had a look through the thread to see if my issue was there and i seen one guy say about it but i cant fiqure out how to fix this as ive looked through the config and cant see anything that does this and i followed srtbull video but everything works except damage on building walls everything works fine like the external walls and doors and windows and window frames but only walls its very strange 

i also have turned on the pve in my server config could that be causes this issue but that wouldnt make full sense if i can damage doors and windows 

server.pve would likely block it and I can't override that
other plugins can block it too
the only setting for this is Building Blocks Are Immune To Damage which is not enabled by default

thanks this fixed it yes it was messing with it all i had to do was turn it off
