Firefox 13.0.1 does not display items for me
Chrome 20.0.1132.47 m also not displaying items

I'm using K2 version is K2 v2.5.7

Just logged into IE9 and its not working. So installed Opera to check that browser. It works for now.
Yesterday was the first time using IE9 to access K2 items.
Will Opera work again?

Hi. Just checked under Firefox 13.0.1 with no issues. Try to logout. Then clean the browser's cache. And then login again. Also ensure that K2 system plugin is installed and enabled.

I don't think the problem lies within which browser is being used. But I have noticed that switching to a new browser seems to allow one to see the category/items for awhile.

This is the order I've gone:
1) Mac-Firefox... was unable to see the category at any point

...switched to

2)Mac-Safari... was able to see category and items initially. After managing other areas of the joomla backedn for a bit and coming back to k2 to manage category/items again, I was no longer able to see them.

...next day at work

3) PC-Firefox... logged in and immediately could see catg/items

4)PC-Internet Explorer... same thing, could see all catg/items

...same time, checked MAC laptop side by side the PC comp

5) MAC Firefox & Safari.... still nothing showing

...next day (today)

6)PC-IE... logged in and could still see catg/items. Logged into Mac and could not see them. THEN I moved forward and assigned a menu to K2 Category. Immediately went back to k2 category and was UNABLE to view. Unassaigned the menu from k2 catg back to an article catg blog, but was still unable to see categ/items.

So, is it possible the problem begins once a menu is assigned to k2?

Joom 2.5
k2 2.5.6 (started with 2.5.7, but switched to .6 to see if it would help)

Hi, just tried logging out in safari (MAC) and clearing cache. Also, checked k2 plugins and all are enabled. Did not change anything, still unable to view.

Cleared history from Firefox browser (MAC), logged in and WAS able to see category. Opened website ("View Site") and clicked on the menu/web page I had assigned the k2 Category to. Went back to backend, refreshed and was unable to see categ/items.

Repeated the above steps with the PC, Firefox and IE, both of them showed me the catg/items after clearing cache and logging back in. However, they also both immediately disappeared after viewing the k2 catg page on the website and then returning to the backend and refreshing, like the previous paragraph states.

Opera browser did repeat the problem for me.

I agree it is not a K2 issue but something to do with local PC you're working on. I've started working on affected site in Ubuntu and all works fine and continues working fine.

Hi,
I'm still working with this problem, thought I'd fixed it by switching to ubuntu to work on site but NO. The one component we have in common is Aceshop. I'm going to make a few tests to determine if Acershop / K2 together is the problem.

I 've asked Joomace if they have tested Aceshop in a K2 website

No progress solving the problem, if the K2 development team would like to have a look in my development site admin panel to investigate you're very welcome

Items restored OK in Chromium browser / ubuntu by clearing one week cache.

Has anyone found a solution for this yet?

I can't see any articles or categories in the admin backend using Firefox.

I can see them fine in IE9 and on another computer with an old version of Firefox.

I tried clearing cache but nothing seems to work.

Please help..
