Hi Everyone!
I have Joomla! 2.5.8 and K2 v2.6.7. After upgrading to the current version, I can't create/edit any k2 item or category. I get a popup with the message:

Calendar.setup:
Nothing to setup (no fields found). Please check your code

and the page body contains a message in red background saying: XML file did not load

I have tried de-activating all k2 related plugins and k2 itself, + re-installing it, but still no luck.

Can anyone help?

I am getting the same error and never got it before and I have using k2 in at least 3 projects.

Did you solve it ? if yes, please how ?

If not what plugins are you using ?

Thanks and best regards.

Please try this fix:

Edit the file: libraries/joomla/html/html.php

Go to the line ~879 and find this line:
And replace it with this line:
Save the file and test.

still i am getting same error please help.
i have issue in after upgrading to k2 2.6.7

Have you tried @Mohamed Abdelaziz solution?

If it doesn't work try to install the K2 SVN 2.6.8 version located here:
getk2.org/assets/get/

and check again.

yes i have tried @Mohamed Abdelaziz solution but thats not work for me.
i will try svn packaged as soon as possible.
thanks for reply.

i have also tried SVN package provide by you but still getting errors.

hi everyone i m so happy because finally i found exact problem.
i have installed php 5.3.6 and there is no need to pass variable with & sign.
i m getting errors in from
administrator/components/com_k2/views/item/view.html.php file.

in this file line No. 429 to 451 use for plugin and passing $item with & sign so after removing & its proper works.
$K2PluginsItemContent = $dispatcher->trigger('onRenderAdminForm', array(&$item, 'item', 'content'));
replace with
$K2PluginsItemContent = $dispatcher->trigger('onRenderAdminForm', array($item, 'item', 'content'));

I'm glad you have sorted it out and thank you for sharing.

Hi

Ajay Gadhavana solution work but there is a problem.
If you do that you disable your k2 pluggins.

To anyone getting error "XML file did not load" please check your K2 plugins. Probably some of them contain incorrect XML markup. Try to disable some until you find which one is causing the issue.

no that not disable your plugin, plugin also work fine.
and still you have any problem then you also have to check costume plugin related K2 .
Its work for me perfectly.
need more help then please explain your problem
thanks
