We are trying to upgrade to 2.9.2 from 2.2
I moved the old files from Server/htdocs/moodle to a different directed, extracted the files for 2.9.2 into Server/htdocs/moodle, placed old config.php in the moodle directory and when I go to out moodle site to start the upgrade process I get following error.
Parse error: syntax error, unexpected '[' in \server\apache\htdocs\moodle\lib\filelib.php on line 3053
HAs anyone encountered it before.
