As admin, looking at a skills wheel with some skills, the search box for skills calls the skill.ajax.php file and gets a list of results but does not offer auto-complete.
A list of the different possibilities should appear in a dropbox.
Create a few skills.
Go to the skills wheel.
Search for one of the skills created.
No auto-complete takes effect (it did in version 1.11.2).
1.11.x
Search by ajax from FCBKComplete stopped working maybe by jQuery version
FCBKcomplete is deprecated 馃槩 I'm switching to select2.
But there are more places where we are using FCBKComplete, like extrafield of type tag
FBCKComplete now is replaced with Select2
Something is wrong after this changes. Try creating a user and you will see a lot of warnings/notices:
Warning: PDO::quote() expects parameter 1 to be string, array given in /var/www/html/chamilo_111/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOConnection.php on line 115

In the user form I cannot add new tags also ...

I did a composer update too ...
Try now with the last commit
Looks good to me now. Closing. I tested skills search, user tags and course templates selection
I confirm, now I don't see the warnings and the js error.
