I had this problem. I deleted the two lines as moshu suggested and now I don’t have garbled characters. Mosu, thank you VERY MUCH for this information. You saved me from a lot of grief.
The same thing happened to me when I upgraded from 2.1.3 to 2.2. All my upgrades have been via fantastico. Is there any simple way to get this problem corrected? Should I try to roll back to 2.1.3 and wait for a future upgrade?
