Question Uncaught TypeError: jQuery(...).modal is not a function at beforeInsert

After updating to 5.1.8 today, my editor doesn't work fully - some buttons (e.g. inserting links, pictures) causing the following error:

Uncaught TypeError: jQuery(...).modal is not a function
at beforeInsert (markitup.editor.js:60)
at prepare (markitup.js:288)
at markup (markitup.js:360)
at markitup.js:230

The line numbers with the error are depending on the function I've tried to execute.

Kunena Version: 5.1.8
Blue Eagle 5 template: 1.5.2

Any ideas what I could do?

Thanks, Boby

update to Kunena 5.1.9, then check if it has been fixed, else go to kunena - plugins - rebuild

Thank you, but where can I get it from? The download link still only offers 5.1.18:
www.kunena.org/download

a thnx will update it. You can also check the backend, you should see a update.

Installed 5.1.9 and rebuilt all plugins - no change; when I try to insert an URL I get:
What else can I check?

Thanks,

The $(…). modal is not a function is usually caused because scripts are loaded in the wrong order . The browser will execute the scripts in the order it finds them. If in a script you attempt to access an element that hasn't been reached yet then you will get an error. Make sure that you don't have a script above one that it requires.

Plugin dependencies

Some plugins and CSS components depend on other plugins. If you include plugins individually, make sure to check for these dependencies in the docs. Also note that all plugins depend on jQuery (this means jQuery must be included before the plugin files).

Multiple jQuery instances

Sometimes this warning may also be shown if jQuery is declared more than once in your code. The second jQuery declaration prevents bootstrap.js from working correctly. The problem is due to having jQuery instances more than one time. Take care if you are using many files with multiples instance of jQuery. Just leave one instance of jQuery and your code will work.
