Someone knows which is the last released version of "Aardvark Lite" theme for downloading? And where I download it?
However, if you compare base/layout/general.php with aardvark_lite/layout/default.php and add the changes you see in the top section above the <head> tag and also the main section from the page-header to the footer, including changing this line...
<?php echo core_renderer::MAIN_CONTENT_TOKEN ?>
to this line
<?php echo $OUTPUT->main_content(); ?>
for whichever version you are using, it should work.
You will also need to add a version.php.
