error corolla d7

after installing adaptivetheme-7.x-2.2.tar and corolla-7.x-2.2.tar, i got this error:

Fatal error: Call to undefined function block_get_blocks_by_region() in /home3/kenjimor/public_html/areatopic/sites/all/themes/adaptivetheme/inc/template.process.inc on line 155

appreciate it very much if you'd provide suggestions.
