Hi,
A fresh installation, WP 3.5.2, 1.8.4 Enfold
Enfold active theme, I select Import dummy data. Everything ok.
Another fresh installation, active my child-theme, I select Import Dummy data, it creates duplicate menus.
Why is this happening? It appears that the themes Kriesi always have trouble with child themes.
I followed this tutorial (and many others): http://vimeo.com/channels/aviathemes/67221517
I can not put the link of my client, but if you want I give you your Admin login information, via PM. Please let me know as, thanks.
Server problem, solved.
