Kanban Plugin doesn't work

Hi,

We work with Projeqtor and just installed Kanban.

It's ok for the installation and we see the front page updated with this new fonctionnality. But it doesn't work.
When we want to create a new kanban for example, nothing appears (alert message or the new kanban)

Here are logs of the installation et the first attempt to create a column :

We try 3 times the install but with no sucess.

The DB is MariaDB and there is no table Kanban.

Done !

CHECK PLUGINS INSTALLED

]MariaDB [projeqtor]> select * from plugin;
| 1 | Kanban | kanban | ../plugin/kanban_V3.5.zip | 2018-07-13 | 1 | V6.5.2 | V6.3.7 | 3.5
| 2 | Kanban | kanban | ../plugin/kanban_V3.5.zip | 2018-08-22 | 1 | V6.5.2 | V6.3.7 | 3.5
| 3 | Kanban | kanban | ../plugin/kanban_V3.5.zip | 2018-08-23 | 1 | V6.5.2 | V6.3.7 | 3.5
| 4 | Kanban | kanban | ../plugin/kanban_V3.5.zip | 2018-08-23 | 1 | V6.5.2 | V6.3.7 | 3.5
4 rows in set (0.00 sec)

DELETE THE PLUGIN
MariaDB [projeqtor]> delete from plugin where name ='Kanban';
Query OK, 4 rows affected (0.00 sec)


CHECK THE ACTION
MariaDB [projeqtor]> select * from plugin;
-> ;
Empty set (0.00 sec)


Then i tried to reload the plugin. Same problem : Plugin installed in the interface but there is no possibility to create some board.

MariaDB [projeqtor]> select * from plugin;
| 5 | Kanban | kanban | ../plugin/kanban_V3.5.zip | 2018-08-23 | 1 | V6.5.2 | V6.3.7 | 3.5
