Hi all.

Im having issues converting my database from Invision Power 3.4.8 to bbPress.
I have used forum convert tool listed here https://codex.bbpress.org/getting-started/importing-data/import-forums/invision/

I am with iPage and have put in the database name, username, password and server ip in correctly (that I can see)
I have left Prefix blank as unsure. Do I need to fill something in that?

Thanks for any help.
