Hi

When I want to create a new "filtre avancé", the "Ajouter un critère de filtre ou de tri" drop down field doesn't work.
There is no list. And 1 times (only 1, but the problem is all the time) I found this in the log :
2017-10-02 11:37:06.971 ** ERROR ** [V6.4.1] ERROR **
2017-10-02 11:37:06.972 ** ERROR ** [V6.4.1] on file 'D:wampwwwtooldisplayFilterClause.php' at line (73)
2017-10-02 11:37:06.973 ** ERROR ***** [V6.4.1] cause = Undefined index: orOperator

It's work on my test server (other server, with DB imported and same version)...
