For starters it said that the permissions for install/external_data were wrong or the folder didn't exist, so i checked and the folder didnt exist so i created it. Refreshed and the install continued.
However from what it looks like it is trying to do a complete new install, asked for all the database information and now its asking me to delete all the data in the database (posts, users etc.).
Why isnt my forum upgrading? Anyone's help would be appreciated.
