Hello Nathan,

This indicates a server related error.
Check your error_log or ask your hosting provider to locate any PHP fatal errors.
If you can access your site's global configuration, you need to enable error reporting in order to see the actual error.

Hi, if i enabled Fetch items from children categories in k2 content module i get PHP Fatal error: Allowed memory size.
I have set memory_limit is to 1024M on php.ini.
Joomla 3.8.6 and k2 2.8
Thanks

Seems the stock module files are deleted. Simply install K2 on top of your existing installation to re-instate the missing files.

In my Joomla 3.8 installation that uses a third-party responsive template ("JD Construction"), when changing away from that template and selecting another one (e.g. one of those that come with Joomla by default, or any other third party template), I get on frontend:

Fatal error: require(): Failed opening required '/homepages/12/d412842748/htdocs/MobileBECMS/modules/mod_k2_content/tmpl/default.php' (include_path='.:/usr/lib/php5.6') in /homepages/12/d412842748/htdocs/MobileBECMS/modules/mod_k2_content/mod_k2_content.php on line 74

I looked up what is line 74. Here it is:

I cannot see from this what could be wrong. Something with an image missing? But could a missing image cause a "fatal error"?

Any advice what to do?

(K2 version is 2.8.0)

Thanks!

Are you using any 3rd party K2 extensions?

I have done a search on google and a search on this site.:

This only happens if you have the system plugin disabled.
Enable the plugin and K2 will work properly.

For me, very simple solution: changed CHmod on components/com_k2/helpers/permissions.php (was 604 -> causes fatal error)

I disabled the cache, and did a double reinstall of the component and plugins, but no result.

No Fatal Errors then.
I think you need to address this issue to the extension's dev.

see here and check your server

Nice to hear that you solved the issue, but with uninstalling you will lose your content.

I solve it!
I uninstall K2, clear cache, and install K2 again, and now it is working!

Hello.
it is Joomla´s plugins related to K2.
In K2 Info view I see the following plugins:
Finder
Search
System
user

And third party extensions:
AllVideos
Simple Image Gallery Pro (NOT INSTALLED)

Do you have an idea of what can be wrong?

Is this the list from Joomla!'s plugin list or from K2's info view?

Thank you very much for your answer.

I don´t have any extension called K2 Multi Images.

The K2 Extensions installed are:
Josetta K2 Categories
Josetta K2 Items
K2
K2 Comments
K2 Content
K2 Quick Icons
K2 Stats
K2 Tools
K2 User
K2 Users
Search
Smart Search
System
User


Can you give me more information that can help me to fix this error?
Thank you.

Hello,

This is related to an outdated K2 extension, K2 Multi Images in particular is known to cause this issue.

Hello:
I am getting an error in every module of my Joomla site.
When I go to edit any of the modules, I can see the information but it is all unformatted and at the bottom of the page I get this message:

Fatal error: Call to undefined method K2HelperHTML::loadjQuery() in /home1/baklight/public_html/2/administrator/components/com_k2/elements/items.php on line 29

Also, I am having issues with JV component, that I am sure that has something to do with this error.

I located the line but I don´t know what to do to fix this.

Can you help me?

I am not able to edit any of the modules because of this.

Thank you.
