At the moment I use the Beez3 template, which has been modified by me.
I tried the Protostar template, this results in a different button 'cancel' and
works as expected.
I placed the modified k2.css in my Beez3 css folder, I will try to put the css
into the protostar css folder and check again if it works.

After reinstalling Joomla! v3.2, with K2 v2.6.7 without any extras or modifications,
using the Beez3 template, the problem is still there.
No working frontend editing cancel button...
With this information you can reproduce the site that's not working,
I can also make a copy on an empty webdir from my hosting provider
and send you a personal message with login info.

Please try with the protostar default joomla template.

The cancel button does work with protostar,
the problem only happens with the beez3 template.

This proves that we are dealing with javascript conflicts. Check the difference even in the order the javascripts are loading in protostar template and in your own template.

At the moment I cannot find the problem,
that's why I made a clean site where people can try and fix stuff.

This is a Joomla! v3.2 site, set to the default Beez3 template.
K2 v2.6.7 installed.
All clean, not modified!!!
The close button in the frontend editor of K2 does not work.

Usernames and passwords are: getk2
(for example, the admin account: login: getk2 / password: getk2)
file/folder rights are set to 777.

The actual site:
getk2.datact.nl/
getk2.datact.nl/administrator

The site will stay here as long as needed or not abused.
please do not abuse my site, I do not give permission to use it for illegal stuff!

A big thank you in advance!

I have the same problem, if we edit an article close button doesnt work.

any new k2 version?

The Beez3 template has issues.

@seeker
What template do you use?
Check for javascript conflicts in the frontend.

If you do not load template.js the cancel button works,
but I still cannot exactly figure out why.
I hope someone can help seeker and me!

I have Bluestork template in administrator and JA university in site.

I dont know check for javascript conflicts in the frontend.
