I'm just having a play around with the Sky High theme as a base to mod with but need to change the position of the blocks to the standard left, right, middle setup rather than the theme's default of dual blocks on the right hand side.
Had a look through the config and settings files but can't see what actually needs changing, is it something in this section?
$hassidepre = (empty($PAGE->layout_options['noblocks']) && $PAGE->blocks->region_has_content('side-pre', $OUTPUT));
$hassidepost = (empty($PAGE->layout_options['noblocks']) && $PAGE->blocks->region_has_content('side-post', $OUTPUT));
$hasnavbar = (empty($PAGE->layout_options['nonavbar']) && $PAGE->has_navbar());
$showsidepre = ($hassidepre && !$PAGE->blocks->region_completely_docked('side-pre', $OUTPUT));
$showsidepost = ($hassidepost && !$PAGE->blocks->region_completely_docked('side-post', $OUTPUT));
