Hi,

we have a problem related to publishing new K2 items. This isn't occurs always but sometimes the generated page isn't a normal HTML page.
Example:
http://i.imgur.com/KwxToNU.png?1

Sometimes this error occurs in a K2 new item page and sometimes occurs in a K2 category page with a new item published.

Any idea?
Thanks.

Is this item part or the entire page?

I don't know if I understand your question.
The item or the category are the page. In that pages, we also show modules but the main content is the item o the category.
And only occurs, sometimes, when we add/publish a new item.

Hi,
Can you provide a link with this output ?

This is a temporary problem. When you reload the page or clear cache this should solve the problem.
The problem is that we can't have the cache activated.

This link is a saved html made until reload the page. I hope this helps you.
Link to saved html

I can't do anything with that because in the source the code is wrong too, it's really strange.

Thanks for help.

This seems more like a server related issue.
Is there anything recorded in the error_log?

I don't have any error_log file in the logs folder.
Maybe I need to activate this in configuration?
I have configured: Server --> Error Reporting: System default

Sorry for my ignorance.

These are two different settings, the Joomla! one will display the errors on the screen.
Setting it to development or maximum will provide some insight when (hopefully never) the site generates this issue again.
