I updated K2 from 3.7.2 to 2.8.0 on a testsite www.aritmik.nl

After this update the frontend-editor gives several errors:
- save & close buttons are scrumbled with K2-image on the left side
- tags can't be added
- switching to image tab (actually it is not a tab here) closes the editor.

Two images of the editor before and after the update:

What can be the problem? I tested this K2-update also on MAMP locally: same problem.

Thanks for help in advance. Would be very much appreciated.

Do have your own template or did you alter the default template? If so, make a backup of your template and copy the file itemform.php from the folder components/com_k2/templates/default/

You can also rename (or delete) the override of the itemform.php file if you don't any functionality apart from the default one.

Thanks for your replies!
I copied the itemform.php from the folder components/com_k2/templates/default/
Alignment K2-picture and save & close button is now ok and the tabs are back.
But stil i can't add tags, the buttons publish "yes/no" and special "yes/no" are not active.
Also, when i click one of the tabs (content or picture) the form will be closed in it's own pop-up. So: strange behavior.
This was all working fine in K2 2.7.2
Template is from Youjoomla.

Are you getting any JavaScript errors?

Hi Krikor

Thanks again for your reply. It helps me step by step further.

There was indeed a jquery-error: for K2 "jquery not defined". Now i turned it on in the K2-params and the form is working.
But, before the update it always worked with the template jquery lib and the jquery for K2 was turned OFF.
Should it now be be loaded seperately for K2 also?
Or is there another solution?

Regards
Rik

JQuery is already being loaded from the template, so you probably don't need to do anything.
If there was an issue, trust me, you would have noticed it.
