This sometimes happens if you're trying to install Mahara into a database from a previous installation failure.

I'd recommend dropping and recreating your database and trying again.  If you get a different error, let us know.

Re : Could not execute command CREATE TABLE config


During the installation http://localhost/mahara/htdocs/admin/upgrade.php

for the core

I had the error message stating : « Could not execute command » CREATE TABLE , with table « config ».


First, I followed the advice here, as given by Jonathan :

increasing the resource limits in the php.ini

max_execution_time = 120     ; Maximum execution time of each script, in seconds


memory_limit = 256M 


Then, I created a new database, as Richard has adviced :


Successfully installed Mahara!
