It would appear that something has changed with the MySQL server that your database is on. Could you ask the hosting company if they've reconfigured or reinstalled the MySQL server recently, turning off InnoDB accidentally or otherwise?
If they have and are not able to work around it for you, then unfortunately you might need to look for a host that can provide what you need.
Good luck,
Melissa.
I run a mahara 1.4.0 site on a shared hosting for several months (with Mahoodle sso). Il was working fine yersterday but today I have this message :
Good luck!
]]>I guess I will have to continue working with Joomla and Moodle until I can give mahara a try
]]>"Mahara requires InnoDB tables. Please ensure InnoDB tables are enabled in your MySQL server."
My hosting company does not support InnoDB
