Was trying to follow up on this but It's been locked and cannot respond. I have installed 2.7.1 dev K2 to the site and it has fixed the issue with front end editing. However it's seemed to have broken items within the site category listings layout and the articles themselves.

First in the articles the header under the article all the rate, print, font size etc are all lined up left justified, the image for the article is the same and everything below the body of the article has done the same. It looks like since applying 2.7.1 everything within my Dev site I'm testing this on has become left justified. The category layout with articles are all in one line to the left.

Is this an issue with K2? Can see an example of the Dev site HERE and the same article on the live site HERE for comparison purposes.

After the upgrade to 3.6 I am getting a blank page on the front end editing to add a new article within K2. With error reporting turned on I get the following error

"Fatal error: Call to a member function isCheckedOut() on a non-object in .../administrator/components/com_k2/views/item/view.html.php on line 100"

I have reinstalled 2.6.9 K2 already and this hasn't seemed to take care of fixing the issue.

Ideas? Suggestions?

If you didn't blacklist countries, more people would be able to help you.

I have both my server and site firewall locked down with black listing with IP and country blocking due to repeated hacking and bought down my server a couple months ago.

However I had to end up restoring the site back to J3.5.1 and K2.6.9 as I had to get users back in and working.

I am providing both live and dev screen shots of what happens when the site is working with J3.5.1 and K2.6.9 on the live site and with J3.6 and K2.7.1 running on the dev site.

If you let me know where you are I can free up the firewalls

LIVE ScreenShot - Dev ScreenShot

I am located in Greece.

I have cleared the firewalls of the block. Also had to change the link in the original post as they changed after the restore. But you will be able to see the difference in the live site running J3.5.1 & K2.6.9 and the Dev site running J3.6 & K2.7.1.

Can you enable the right click?

I have enabled this for you.

It looks like K2's css are not being loaded.
It could be related to two things.
a) Template's or framework's caching is not reflecting the changes,
b) You have disabled K2's css loading from the extension's settings.

K2 is enabled at Default css. I looking like the Framework is blocking the inheritance. Will have to work with the designer to see if there is a solution. Thanks for the help.

You 're welcome :)
