I just upgraded to 6.1 I have had very very few issues, mostly able to sort out myself.
Main issue with Dolhpin is the language file i made in 6.005. When i click on Join, it doesn't have all the FieldCaption for profile info that the default langauge file has. Do i have to add each one manually? The join page looks ridiculous.
When I make a new file from the English default page it errors out. Any ideas?
