Error while migrating to 1.1.0 alpha 2 from older version - Fix_MySQL_No_Zero_Date.php
When migrating to 1.1.0 alpha 2 I get the following error while opening admin/migration.php:
PHP Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'NULL DEFAULT NULL' at line 1' in /var/www/html/app/classes/Framadate/Migration/Fix_MySQL_No_Zero_Date.php:66\nStack trace:\n#0 /var/www/html/app/classes/Framadate/Migration/Fix_MySQL_No_Zero_Date.php(66): PDO->exec('ALTER TABLE pol...')\n#1 /var/www/html/admin/migration.php(102): Framadate\\Migration\\Fix_MySQL_No_Zero_Date->execute(Object(PDO))\n#2 {main}\n thrown in /var/www/html/app/classes/Framadate/Migration/Fix_MySQL_No_Zero_Date.php on line 66
Any hints?
Thank you
