 * I’ve got a brand new install of WP 3.5.2 on my development PC with no plugins
   and using the TwentyTwelve theme. So nothing special or different.
 * I’ve just installed the plugin OK, but when I try to activate it I get this error.
 * Plugin could not be activated because it triggered a fatal error.
 * Looking at the error log I can see multiple entries (about 72) like this:
 * WordPress database error. Can’t DROP ‘ObjectOwner’; check that column/key exists
   for query ALTER TABLE wp_iprojectweb_projects DROP INDEX ObjectOwner made by 
   do_action(‘activate_iprojectweb/iprojectweb.php’), call_user_func_array, iProjectWeb::
   install, iprojectweb_install, referer: [http://127.0.0.1/wordpress/wp-admin/plugins.php?error=true&plugin=iprojectweb%2Fiprojectweb.php&_error_nonce=149f161f83](http://127.0.0.1/wordpress/wp-admin/plugins.php?error=true&plugin=iprojectweb%2Fiprojectweb.php&_error_nonce=149f161f83)
 * There’s a whole bunch of new tables in the database and the db user has full 
   privileges. So anyone know why this plugin won’t activate please?

 * I have this plugin up and working successfully on WP 3.7.1.
    Not sure if it is
   blind luck or not, but it is working and my team is using it.
