Hi :)
After cms update, I do not loads images.
Loads images only if the load on the server, but I preferred to upload files.
I provided the permissions to 777 k2 folders, deleted cache, checking the name of the file, but nothing...
I have k2 2.7.0 v. and v.3.5.1 joomla.
Thanks for your help.

Hi,
Can you send a link of your site ?

You need to know some parameters?

I enclose two screenshots. maybe I can not explain ;(
