I am in the process of theming my site with AT Panels Everywhere.
I created a Home Page content type and created a Home Page variant in Node template. I have the Selection rule as Node: type as Node being viewed is type "Home Page". I've created Mini panels and added them and other content in the Layout regions of that variant. I created a Home Page via 'Add Content' in order to see the result.
The issues are:
1) The content I added to the Layout regions in the Home Page variant show up as stacked up on the left in the Preview and on the Home Page itself, not in the Left, Center, and Right as it shows in the layout. I have the Disable Blocks/regions checked for both the Default site template -> ATPanels Everywhere Site Template AND for the Home Page variant.
For the Home Page variant, I have Template as 'Let the system choose' since I had already selected 'Layout for home page in default' -> 'AT Panels Everywhere site template' as the Current Layout via Manage Display in the Content Type screen.
*** EDIT: Selecting the 'Layout for home page in default' via the Content Type page was made just prior to creating this support issue. I just noticed that gave errors that went away when I set the default back to 'None'.
2) I don't see the resulting layout from the default AT Panels Everywhere Site Template (menu, etc.) on the Home Page that was created from 'Add Content'.
Q: What might be the issues be?
