I'm using Joomla 3.8.0 fresh install with the latest k2 2.8.0 and Responsive Grid for k2 and Joomfolio 3.3.1.

When I select Data Source -> Specific item and try to Select an Item it opens a lightbox with the wrong k2 items page as you can see in the screenshot in the attachment. The page is a standard k2 list where you edit and create the items and I can not select the items for the module. When you click on the item it goes to k2 item Edit page.

I fixed it by deleting the k2 2.8.0 Component and installing K2 Component v2.7.1 and then updated to 2.8.0 and everything worked fine. There is something that the 2.7.1 has that 2.8.0 version is missing, I don't know what it is, the developers of the module should know.

If you already have a lot of articles and you can't delete the k2 2.8.0 component because it will delete all the articles, as I did, you can install a blank Joomla 3.8.0 on your localhost and first install k2 2.7.1, update to 2.8.0 and then just copy and paste the Administrator -> Components -> com_k2 folder.
That fixed the bug for me. :)

Forgot to say, the k2 v2.8.0 doesn't have the /media/k2/assets/css/k2.modules.css that is used in the modules list style of articles so you can make a custom ordering, without it doesn't work, you can drag the items but when you release the click it goes back in previous place.

Failed to load resource: the server responded with a status of 404 (Not Found) k2.modules.css

You can continue the good work now, thank you... ;)
