Can anyone point me to where I can download just the K2 Content module for Joomla 3.8?

It looks like my copy has become corrupt as the settings tabs and parameter setting tabs are not displaying correctly.

Hello,

You will to reinstall K2. The module is not available on its own.

I was afraid that might be the case.

Many thanks.

You 're welcome Mick :)

Before I do the above, can I ask if there is any idea what might be causing the problem with the K2_CONTENT module?

I am using K2 2.8.0 in Joomla 3.8.0 with latest Joomlashine components. Joomlashine have looked at the problem and are saying it is the K2 module.

Annoyingly I have another development site, with the same Joomla, K2 and Joomlashine content and the K2_CONTACT works correctly.

Using developer tools I can only see these differences on the error site:

On the error site only I get this :

"SCRIPT438: Object doesn't support property or method '_addClass'
jquery-ui.min.js (12,10575)"

On the error site the first item in the stack is Cloudflare, whereas it is the last on the development site.

In Admin the K2_CONTENT module opens but there are no tabs for Menu Assignment, Advance, Permissions and the settings on the Module page only display as text. Save does not work. Screenshot:

Any ideas?

Are you using any other 3rd party K2 extensions?

No, only K2 package component, modules and any plugins. All 2.8.0. Only the K2_content module has the problem and only on the live site, for me. What is really odd is that the Joomlashine guys have had a look in Admin and for them the K2_content module works correctly.

In IE11 another error showed up:

SCRIPT438: Object doesn't support property or method 'evaluate'
tabs-state.js (1,643)

I have now tried on 3 computers and 5 Browsers and no change. I have cleared cache and history and no change. I have set up a new super user account in Admin and no change. The only common feature would be my public IP address.

So stumped!

Can you check in K2's setting and verify that both jQuery and jQuery UI are being loaded?

I can only find a Load jQuery Library in K2 Parameters.. I have tried loading a library and no change, even with clearing cache.

Where is jQuery UI setting?

The problem site is set up exactly the same as the site where the module works.

Are you using the exact same extension, versions etc?
Is Cloudflare optimising administrator scripts as well?

Yes when this problem was first found both sites had the same extensions and versions. The development site was originally a clone of the site that is giving problems. Now the development site has additional components on trial.

The Cloudflare ordering difference is in Admin. I don't know what component is launching Cloudflare or how to change the order.

If possible exclude CloudFlare from the admin section.
It will cause issues.

I can't disable Cloudflare just in Admin.

The problem component appears to be administrator\components\com_k2\helpers\html.php where line 129 :

$document->addScript('cdnjs.cloudflare.com/ajax/libs/jqueryui/1.12.1/jquery-ui.min.js');

throws this error:

TypeError: this._addClass is not a function

This doesn't have to do with Cloudflare, it is just using Cloudflare's CDN. And it looks like a JS conflict.

Maybe you are using a modified template for the Joomla admin panel (I see in your screenshot it is not vanilla Joomla) that loads different JS files. Go to Extensions -> Templates and make sure you are using Isis.
