Ok, again.
If you 
SEE this file : 
GuildProfiler.lua AND its approximately 1 KB in size, and it 
CONTAINES this (because, YES, you can 
READ these LUA files !! [a nifty tool will be about any text editor]) :
rpgoGPpref = {
	["enabled"] = true,
	["rescan"] = 10,
	["debug"] = true,
	["compact"] = true,
	["verbose"] = false,
	["history"] = true,
	["title"] = false,
	["button"] = true,
	["lite"] = true,
}
then you should 
NOT use it, not touching it - and that very good, no-one told you to do so anyway.
Just leave it.
I always delete it, but it keeps popping back again, as if the Windows File Protection System is taking care of it ....  
Anyway, forget about it.
BUT
If you find in the same directory a file that is being called CharacterProfiler.lua which is 
several 100th of KB in size then 
SCREAM for 
VICTORY. 
That's the one, upload it, with your Roster-Officer password (or admin password) and you'll be having a positive result in no time.
NOW
Re-read the wiki that Zanix stated, and see what you didn't do..... 
And answer 
THIS question: 
WHERE did you
 MIS READ the Wiki ?
Please tell us about 
THAT - it will help 
MANY others afterwards.
