Comment (by viajarapie):

 Hi again,

 The Theme developer delivered a new version (Lovecraft 1.19) even though
 the upgrade wasn't related to the javascript problem I experienced with WP
 4.9 apparently.

 I installed Lovecraft 1.19 while still running WP 4.8.3 and everything
 worked fine.

 I have just upgraded to WP 4.9.1 and the javascript problem in my backend
 has come back, just as described in this thread above.

 I have notified the Lovecraft theme developer in hopes he can help.

 I will need to downgrade WP again to the last version that was working for
 my installation (4.8.3)

 If you have any idea about what could be wrong, I welcome your help.

 Thanks for your time!
