Solved Malfunction of the keys for inserting attachments and images

Hi, suddenly the following buttons have stopped working on my forum:

Link image
Link
Video Provider
Video Video
Map
Setting up surveys
Emoticons

and the button to attach file "attachments "....
The template is Gantry 5 and I installed the latest version of Kunena, I created a provisional profile, if you wanted to test the problem you can do it by accessing the site:

www.tbait.altervista.org

With the following credential:

User: Provvisorio
Pw: provvisorio

Thanks for the help, I can not understand what could have happened.....: ' (: ' (: ' (

Your page loads the script jquery-latest.min.js from the page code.jquery.com/ This script cause a conflict with the editor.
I think this script checks only if your jquery librarys are up to date. blog.jquery.com/2014/07/03/dont-use-jquery-latest-js/ If you disable it, the editor works.

Hi Rich, thanks for your reply, I'd know how to disable jquery-latest. Min. js from my Site? Thank you!

I don't know, which extension use this script on your page, maybe thereis included a option to disable it. But if you can't find this extension, it should also be possible to deactivate the script with this plugin.
extensions.joomla.org/extension/js-css-control/

Thanks rich, forgive me but I'm not experienced, I installed the plugin but nothing happens.... could you give me some advice? Should I do anything else? Thanks again especially for the patience!

I don't know if this can be a causary extension to the problem
