K2 is not functioning properly in the latest Joomla version, there are errors on almost every function. Have updated to the latest PHP instance, so will there be an update to address this question?

I really do want to build a blog site with K2. As this is a new project decided to upgrade Joomla and PHP to the latest versions.
However after installing K2 simple things like imported articles won't open, menu items etc throw errors, so am a bit dismayed.

Hello Julie,

I need you to elaborate, can you post the error messages?

Articles imported from Joomla couldn't be opened due to JSON error

There doesn't seem much point in doing anything until the compatibility issue has been resolved.

This could be also an issue with your hosting provider.
I've tested latest K2 dev version on latest Joomla 3.7 with multilanguage and I've got no errors, no warnings, no notices.
But it was only on sample data.

Hi!

When creating a K2 article, "page break" and "read more" will not work. If I insert "read more" into the text, you can not save the article. This is typical for longer texts.

Has anyone else experienced such a mistake?

I isolated the menu issue to a template that was built for Joomla 3.7. Changed back to bog-standard template and the issue resolved itself.
Also, I want to use Facebook comments as articles will propagate to a wider audience. The comments module is switched off so assume one has to use CSS to remove links.

@Szasza Are you getting any error messages?
@Julie You can use CSS or you can better yet (if you have hardcoded the comments in your overrides) remove or replace these links in the category_item.php and item.php files.

Hi,
after the last update of joomla, the k2 component continues to go wrong when I try to save an article:

Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; upload has a deprecated constructor in /home/ufypphfg/domains/studiogroenlandia.it/public_html/administrator/components/com_k2/lib/class.upload.php on line 624 Fatal error: Maximum execution time of 30 seconds exceeded in /home/ufypphfg/domains/studiogroenlandia.it/public_html/libraries/joomla/database/query/element.php on line 95

Before Joomla's last update, everything worked correctly.
How can I fix it?

Thanks
Damiano

@Krikor
Thanks for the advice regarding removal of comments links. Much appreciated.
The main concern is the menu errors that return - Call to undefined function limit_text() This only occurs when I use SJ_the _cool template and have asked the developer for advice.
Also, articles imported into K2 return a JSON error and won't open (regardless of template). I can work-around by copying and pasting, but the error is indicative of an unhappy system.
This is a new project so there's no point in using earlier versions of Joomla.

Thanks Fotis, I've already tried to increase it to 90 seconds but nothing has changed.

@Julie look at the forum for the JSON error, there are several solutions posted.

@Damiano (Stupid follow-up) Try 120sec

My hosting provider doesn't allow us to increase the value over 90. Anyway it was working before the update , now it returns an error saying there's a deprecated method.

Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; upload has a deprecated constructor in /home/ufypphfg/domains/studiogroenlandia.it/public_html/administrator/components/com_k2/lib/class.upload.php on line 624 Fatal error: Maximum execution time of 30 seconds exceeded in /home/ufypphfg/domains/studiogroenlandia.it/public_html/libraries/vendor/joomla/string/src/phputf8/mbstring/core.php on line 41

No one else has this problem?

624 Fatal error: Maximum execution time of 30 seconds exceeded in /home/ufypphfg/domains/studiogroenlandia.it/public_html/libraries/vendor/joomla/string/src/phputf8/mbstring/core.php on line 41

Is this an accidental c/p? If not, this means that the 90sec limit was not enforced and the limit is still 30s.

ok, my hosting provider resets the limit to 30 seconds but with 90 seconds was the same thing

Hello,

I am facing a similar issue. After updating my joomla site from 3.6.5 to 3.7., I cannot save anymore my k2 items (I am using k2 v2.7.1). My k2 items have introtext separated with <hr id="system-readmore" /> from the fulltext.

I uninstalled all my extensions one by one to find if there is a conflict but i didn't manage to resolve the issue. I strongly believe there is a conflict between k2 component and new joomla 3.7 version.

However the behavior is strange because with another site the save functionality of k2 items is still working ok after update.

I can not realise why this happens.

I tried to eliminate the introtext and the <hr id="system-readmore" /> and in some cases the issue is resolved and in some cases the issue persist. Maybe something is happened in this piece of code.

When trying to save my k2 items it takes extremely long time and finally I am getting the message (in my production server):

Gateway Timeout
The gateway did not receive a timely response from the upstream server or application.


In my XAMPP environment I am getting a blank page

Thank you very much for your help
JP

I have noticed that after eliminating any inline css, <hr /> and classes (i.e. <div class="foo">, inside my k2 item, the k2 item could then be saved, in my case. Otherwise k2 save functionality is not working.

Could you please suggest a fix?

Thank you very much
JP

My issue was resolved by fixing a JSON error . Thanks to Krikor for putting me on to the JSON error string and to Jan Marin the author of the fix.
