I am quite new using Drupal, and especially Panels, so maybe I am missing something obvious. The thing is I have installed the following modules and themes, but somehow I am not able to use neither the AT responsive panels layouts nor the AT Panels Everywhere layout with Panels. Everytime I try to use them I get a one column layout, with a 100% width, which I cannot alter either.
If I use the two or three column layouts provided by Panels, that works fine.
Is there any problem with the versions I am using, or do I have to check some option I can´t find?
Panels everywhere 7.x-1.0-alpha1
AT Panels Everywhere 7.x-1.x-dev
AT Core 7.x-3.0-rc2+2-dev
I would really appreciate your help, as I have been several hours searching for the problem, with no results.
