I already bought the Pro version because your Grid seems to be the only usefull one 😉
Now i tested again on a blank second WP installation. and you’re right, it is working! so i was right too..it used to work on my project but now it somehow stopped working. whatever i do and play around with the shortcode settings, i can’t get it to work again. now i’m starting to freak out a bit -.- but i really don’t know what i could have done that one installation is working fine – the other one not..
