1. My original purpose is to create product list with thumbnails via K2.

The pic was added by the ‘image’ button under the edit window. (pic 1)
This button should belongs ‘Artof Editor’ PLG.
However, the thumbnails never come out except for the title.

Occasionally, I found the thumbnails list was created only after I add pictured via K2. (Pic 2)
However, the popup window keeps on loading with blank after click ‘browse server’.
It only can be functional only after I used VPN.
I guess there must be some remote js is running, but I don’t know how to find and fix it.

2. I believe another issue is the same type.
After click the article created by K2, the page shows all content but my Chrome always showing loading symbol.

These issues are helpless in my local forum.
Appreciate someone can help.

All above test is on local computers.
website is created by RT EPSILON template.
jQuery & jQuery UI was set as local.
Xampp is 1.8.2.

Hello,

I would suggest using a K2 Content module which offers a lot more functionality and you do not have to upload each thumb manually.

Are you based in China?

thank you Krikor, thaks for your reply.

What's the name of the K2 content module ?
is it helpful to create thumbnail on article list page?

Yes, you are right, i'm in P.R.China.
pity. But maybe better than Iran.

some local freind mentioned error relates below JS and caused failure.
ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/smoothness/jquery-ui.css
ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js

It's K2 Content. It will really help you manage your content.
Yes, I asked of China because all Google related CDNs are banned there.
I do not really know what's going on in Iran. Not completely clueless though.

well, K2 Content is K2. right?

I'm using K2, and the issue is about K2 itself.

the source file contains ajax.googleapis.com which is blocked in CN.

Maybe developer can consider to add some adjustable setting for webmasters whom has difficulty to connect google.
just suggestion.

There is a setting in K2 to load local copies for both jQuery and jQuery UI. This option is located in K2's parameters.

If another extension is loading jQuery as well then it might create an issue as well.

They were both set to load local copies before this issue.
I don't think there is another extension is loading JQuery on this backend page.
I was editing new article in K2's interface and nothing to do with other extension.
