I'll try to do the same.
I'll remove my admin script (so the housing script won't connect to it) and test it out.

Did you create the folder PPC_Housing in your scriptfiles folder?
If you didn't, the command will not give that error but it will crash your server.

Have you got all plugins installed properly?
Did you also restart the server?
Don't add the .pwn in your filterscripts, it works without that as the server will load the PPC_Housing.amx.


EDIT: Just removed my admin script so I don't have the admin-level status and the housing script would be forced to use internal admin-checks (use RCON admin status).

Without logging in as rcon, the command gave me SERVER: Unknown command as it should.
After logging in as RCON admin, the command worked normally.

Does your server-console have these lines in it:

Code:

----------------------------------------
PPC Housing filterscript initialized
Houses loaded: xxx
----------------------------------------

Where xxx is your amount of houses.
