Thread:Extension talk:Flow/Internal errors

Hi! I'm very glad to see that the first release of this awesome extension is out!! I've done my best at installing it, but couldn't. I followed the instructions carefully: I installed a brand new wiki in my localhost, installed VisualEditor, the Parsoid, and checked that everything was running ok. Then downloaded Flow, changed the 'wiki' in flow.sql to my database name, run the update script, all ok. But when I enter my wiki, I see nothing new, and when I go to Special:Flow I get this "internal error": TODO: Redirect to users board? Backtrace: And when I go to Special:Flow/Main_Page, I get this other "internal error": Unknown flow type 'discussion' requested Backtrace: Any diagnosis? Thanks!!
