Finally i managed to reproduce the issue. It occurs when the module multilingual status is enabled and the system debugger is disabled.

This commit solves the issue: github.com/joomlaworks/k2/commit/4bbfd5cf0cf3911dbbf5393a4bcd882ec111ff99

Thank you all for your valuable feedback.

I updated my dev site with this build and it did indeed fix the issue but it also did some messing with the style of the item form so that the tabs no longer show up. All the individual divs display, however. I upgraded just the 14 files changed in the commit on a clone of my dev site and it failed to fix the issue. Its possible there is some other conflict going on with my own site so I'm happy enough just disabling Multilanguage Status module until 2.7.0 comes out.

Thanks for your help with this one.

Open your browser's developer tools and check under the console tabs for any errors.
If nothing shows up refresh the page.

All sorted now. I had an override I had forgotten about. Everything looks great!

Thanks for all your help!

Nice to hear that the issue is gone Paul :)

Hello,

I have the same problem for editing K2 Items.

My dev env is quite recent. I have downloaded latest Joomla 3.r.1 and K2 yesterday. No sample data is installed but multilingual with two languages. I really need this.

K2 Item and Category create edit view and web site front end working without any problems with two languages.

But K2 Item editing always pops up "Item must have a title" message.

How to solve this? what to try? The fix above ? Please explain how to?

Thanks

Yes the above solution worked for me. Here are the steps I took:

1. Downloaded a copy of the K2 dev master zip file from the link above. You can also download the absolute latest from this link which seems to contain a few more fixes... github.com/joomlaworks/k2/archive/master.zip

2. Extracted the zip file to my /webroot/tmp folder and used the Install from Directory feature of the Extensions Manager. You might also be able to to just upload the master.zip file like any other extension but I don't know because I didn't try it.

Make sure you take a backup first!

Cheers
Paul

Thanks for your reply,

I have doubted, this is procedure is not an upgrade, replacing the code.

Of course I will do backup but let me ask, what about existing content ? do I have to do something ? or replacing the existing K2 code with the new one just enough to use it ?

You can simply deactivate the Multilanguage Status module.

You can simply deactivate the Multilanguage Status module.

its a K2 bug .. i hope its not the solution for the future ..
