Hit this error during the "install profile" portion of the install, using PostgreSQL-9.2.14: "The installation has encountered an error. Please continue to the error page." "An AJAX HTTP error occurred. HTTP Result Code: 200 Debugging information follows. ... Organic Groups Mass Add settings are available under Administer > Site configuration > OG Mass Add SQLSTATE[42P07]: Duplicate table: 7 ERROR: relation "opigno_statistics_login_history_opigno_statistics_login_history" already exists" I started from scratch twice to make sure I did everything correctly. Got the same error both times. If I click on "error page" it takes me to the "Configure site" page and has these errors at the top: "Warning: Invalid argument supplied for foreach() in user_permission_get_modules() (line 3091 of /var/www/html/opigno/modules/user/user.module). Warning: Invalid argument supplied for foreach() in user_permission_get_modules() (line 3091 of /var/www/html/opigno/modules/user/user.module)." Next Page, "Configure site" has this error listed: "SQLSTATE[42P01]: Undefined table: 7 ERROR: relation "opigno_statistics_user_course" does not exist LINE 1: UPDATE opigno_statistics_user_course SET username='admin' ^" Any clue how to fix these?

Error on install of 7.x-1.21 with PostgreSQL

I see that Drupal instructions (elsewhere) specify that PostgreSQL database can be used, while Opigno specifies only MySQL (and MariaDB). I've since switched to MariaDB underneath my Opigno instance. Too bad, 'cuz PostgreSQL is quite bullet-proof compared to MySQL.
