I bought an theme and it has his own pagebuilder. No if change thems i have i problem.
Somebody told my only to use themes that allow you to use visuel composer from wpbakery (http://codecanyon.net/search?utf8=%E2%9C%93&order_by=sales&term=+Visual+Composer&page=1).
In that case i could easy change to other themes without getting in trouble with shortcuts that don't work anymore.
Is this true? May somebody has some advice on this?
