Hi guys!
I created a menu item for the K2 categories listing to make the front page look the same as in the K2 demo. But I keep getting the following error message:

"Fatal error: Class 'ContentHelperRoute' not found in /home/georgia/public_html/plugins/content/ultimate_social_bookmarking_plugin.php on line 243"

This makes no sense to me whatsoever. The categories have been created and published. I added one article to each for test purposes. And tried featuring the articles too. Nothing seems to work.

I have no idea what is going on.

In fact I tried to create menu items for each K2 option. But the only one that actually works is the authors' blog.

Any advice and pointers are much appreciated!!!

Thanks,
Astrid

i would try to look that all files are installed while K2 installation.
I would copy alle files manual to their folder. Maybe this could help !?
But do this at your own risk :D

Hello, I am also getting an error when trying to create a new ITEM.

I have PHP5
Joomla 1.5.12
K2 V. 2.0.0.

Fatal error: Call to undefined method stdClass::onDisplay() in /Applications/XAMPP/xamppfiles/htdocs/mysite/libraries/joomla/html/editor.php on line 261

If anyone can help, it would be great to start using K2! Thanks.

Getting closer. Looks like it depends on a "View"

I tried copying the relevant files from the older k2 version and I'm stuck on this PHP error


Fatal error: Class 'K2Controllerdefault' not found in C:\wamp\www\components\com_k2\k2.php on line 42

I have everything backed up but I was having a problem and unistalled k2 and now when I go to log in front end or back end I get errors. I can't even get to my site to reinstall k2.

I should have known better but I didn't, any ideas cause I am not rebuilding my newest project at 50 + pages and over 100 articles...not a good day.

Here is my error message, it's obviously cause I removed k2

Warning: plgSystemK2_Joomfish::require_once(/home/default/theskunkhouse.com/user/htdocs/administrator/components/com_k2/lib/JSON.php) [plgsystemk2-joomfish.require-once]: failed to open stream: No such file or directory in /home/default/theskunkhouse.com/user/htdocs/plugins/system/k2_joomfish.php on line 31

k2 was working fine, then I started getting the white page problem (json) I followed the instructions to copy and paste code, worked, but then I couldn't create a new item, so I uninstalled and here we are now.

Hi again. In order to have your galleries displayed you need to use the latest version of SIG Pro. The standard free version of SIG hasn't been updated yet to work with K2. The update for the free version of SIG is coming in the near future. Now, regarding the fatal error you posted this is weird. Maybe a an uncompleted installation? Please try to reinstall the component.

Whenever I create a new item in K2 I get the following message
Fatal error: Call to undefined method K2ModelItem::checkSIG() in /home/default/theskunkhouse.com/user/htdocs/administrator/components/com_k2/views/item/view.html.php on line 91

This happened after I did the recommended fix for getting rid of the white page bug.

I can't edit or create new items though.

I was using the 1.0.2b version of K2 and just uninstalled it and installed the new version 2.0.0 Build 20090701 (pre-release). I added a category, added an item and then tried to view the front page and got the following error:

Warning: require_once(/var/www/sites/xxx/components/com_k2/controllers/default.php) [function.require-once]: failed to open stream: No such file or directory in /var/www/sites/xxx/components/com_k2/k2.php on line 40

Fatal error: require_once() [function.require]: Failed opening required '/var/www/sites/xxx/components/com_k2/controllers/default.php' (include_path='.:/usr/share/php:/usr/share/pear') in /var/www/sites/xxx/components/com_k2/k2.php on line 40

Any ideas?

You get this error cause some other is using the same "php class". We have resolved this in the latest K2 update.

You're advised to upgrade by simply overriding the old files with the new ones.

Fatal error: Cannot redeclare class Services_JSON in ........administrator/components/com_k2/lib/JSON.php on line 128

I get this fatal error anytime it try to publish an item to a category both when saving the article in the admin and when I click on the menu item in the front end.

Any thoughts?

Hi,
I had the same problem, white/blank page on K2
When setting the joomla error showing to max, i only get notices, no fatal error

Finally the problem was coming from multithumb plugin that was enabled, and seems to interact with K2

So try to check /disable some of your content plugins

I get the same problem, was working fine (awesome app by the way) for a couple of days. All pages with k2 items went blank. Here is the error I am getting

hi. After some tests i figured out that the problem was on the backend of K2. Is that correct? K2 imports all content plugins in order to render the video and the gallery. This is now fixed in v2 final where K2 imports only specific content plugins that are needed (SIG and AllVideos). This is a fix from K2 side. A fix from the other side could be simple check in the plugin to prevent rendering in the backend.... Thanks for reporting this issue to us.

Tried both 1.0.2 and new 2.0, same result:

Fatal error: Class 'JSite' not found in /var/www/scrcorp.com/cms/plugins/content/phocagallery.php on line 37

Uninstall the Phoca plugin, and all is well.

So... do we choose between Phoca and K2, or what?

I have the latest pro and when I will put an image on the gallery tab I got the following failure

Warning: require_once(/home/jinbang/forum.123chinalove.com/j15/components/com_k2/controllers/items.php) [function.require-once]: failed to open stream: No such file or directory in /home/jinbang/forum.123chinalove.com/j15/components/com_k2/k2.php on line 40

Maybe somebody can help me

I can't install sig pro either and I don't have any file permission issues on my server. I have installed hundreds of other plugins, modules and components over the last few days without issue. Plus I have been using this product for a few years now, this is the only version that will not install 2.04 Pro

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 1046044 bytes) in /home/xxxxxx/public_html/libraries/joomla/filesystem/archive/zip.php on line 325

The latest K2 installed and all its parts.

PHP version  5.2.4
MySQL version 5.0.81-community
GD image library bundled (2.0.34 compatible)

Now I will search the forum, this post was just to confirm I too have the same as others asking questions here.

Thanks
