Whenever I do so, I get a momentary flash of a red error message saying something like "___ needs at least 3 characters and no more than 255 characters". It doesn't stay and it doesn't apply. I have to keep hitting save in order to read it.

I have php version 5.2.something, am on bluehost.com, magic quotes gpc is off (and I copied the .ini file to all parent directories just to make sure). So what am I missing?
Thanks,
Mark
