Same problem here…
Using GP, GPP and GB. Imported Access theme from the library, which is a 1 page full width theme. Instead of starting to edit the original page, I wanted to edit a copy/clone. So used 4 different plugins that duplicate pages/posts, used all kind of copy options (just cloning and creating drafts first), but over and over the copied page is not full width anymore…
Please see if you guys are able to copy the homepage of Access theme and let me know what to do to get it working.
Cheers,
Marc
