This is the error that shows under debug when attempting to open the com-k2 component:

Using Joomla 3.3.4
PHP Version: 5.3.29

On Install - it reports all installed properly.
No plugins show up in extension manager. (Search for K2)
COM_K2 does show up in extension manager - Manage and it does report all items removed on un-install.

Hat das auch schon mal jemand gehabt?

Jquery not defined 10 months 2 weeks ago

Bonjour à tous,

J'ai désactivé dans K2 le chargement de JQuery car mon template lance déjà jquery

Le problème c'est que j'ai un message d'errreur : Uncaught ReferenceError: jQuery is not defined k2.js?v2.6.7&sitepath=/:9
(anonymous function)

J'ai vu que c'est le plugin System - K2 qui lance la requete et j'ai vérifié l'ordre de mes plugins et mon jquery de template est bien avant (ordre 0) et System - K2 (ordre 11)

J'aurais pu désactivé System - K2 plugin mais ensiute je ne peux...

The component will work fine with Joomla! 3.2.x and 2.5.x.

These issues appear when there are other K2 extensions installed that do not support K2's latest versions.

I believe there is something within this component.
I just noticed that by logging out and then in, everything worked just fine.
With most components, you don't need to do that

No, redownload and try reinstalling.

Just installed latest K2 version (2.6.7) in Joomla! 2.5.17 and the same error is popping up.

What can I do to get rid of this problem? Should I manually -ftp- transfer those files?
