Sorry
If I bought pro version...
1- I have always updates or have I to renew every year
2- It works with visual composer?
3- the post grid is loaded by ajax? It's because I use visual composer and the post grid is loaded by ajax and I do not want to load with ajax because all the homepage load very slow.
4- Is it possible to insert a grid on a widget area?
