The hack wasnt via SMF boards - it was via something else, which changed the htaccess files.
Nothing was ever compromised on the boards at anytime, the htaccess files was not even in those directory.
But, i needed to upgrade various items, including the boards, and other parts. Keep in mind, it hasnt been tweaked in a few years. Oh, it will go back to yellow colors, but with new updated script and settings.
