i had full joomla site.  wanted try different, backed everything.  database, of root directory, everything.  new thing didn't work out, copied over.  reinstalled database, , won't work.  keeps telling me cannot connect database.  correct, , nothing has been changed since last install.  don't know if chmoding has when copied over.  can give me suggestions?

thanks.

you've possibly changed database settings in config file (at guess), either or host has given new name your db or username?
