Errors after upgrade to 7.x-1.21

I just tried an upgrade from Opigno 1.20 to 1.21. I have Drupal 7 and PostgreSQL 9.2.14 on the machine. I did this: 1. Download and extract locally Opigno 1.7 files 2. Put the website into maintenance mode (Configuration -> Development -> Maintenance mode) 3. Transfer all the files (except .htaccess and the folder 'sites') 4. Run update.php 5. Deactivate maintenance mode I couldn't do #5 because I was locked out as "admin". Had to do this: su - postgres psql UPDATE variable SET value = 'i:0;' WHERE name= 'maintenance_mode'; DELETE FROM cache_bootstrap WHERE cid = 'variables'; DELETE FROM cache WHERE cid = 'variables'; \q That got the Opigno site back up and running, but crippled. I can sometimes get to the black menu across the top, sometimes not, and the icon keeps going across the full screen. I now see this: Type php Date Thursday, January 14, 2016 - 14:28 User admin Location /?q=admin Referrer /update.php?op=results&token= Message PDOException: SQLSTATE[42P01]: Undefined table: 7 ERROR: relation "opigno_statistics_user" does not exist LINE 3: opigno_statistics_user opigno_statistics_user ^: SELECT 1 AS expression FROM {opigno_statistics_user} opigno_statistics_user WHERE ( (uid = :db_condition_placeholder_0) AND (month_year = :db_condition_placeholder_1) ); Array ( [:db_condition_placeholder_0] => 1 [:db_condition_placeholder_1] => 1451635200 ) in opigno_statistics_app_exit() (line 280 of /var/www/html/opigno/profiles/opigno_lms/modules/opigno/opigno_statistics_app/opigno_statistics_app.module). Severity error Hostname Operations Opigno LMS 1.21.0 Any recovery from this or must I start over? I have a database backup and an Opigno backup from earlier today, just in case.
