Inserting widgets in java on a page

Hello everyone,

I’ve been searching a solution for this problem for a while and nothing ever worked; I inserted around 8 plugins on a page of my website, the one from google works perfectly (calendar, maps engine), but the ones from other websites (weather, changing rate, clocks) are working only when:
I need to remove manually some “CDATA” codes that are inserted automaticcaly in my code.
It seems that it’s a wordpress issue with java(i use visual composer but i tried without too), and everytime i do a tiny change on this page, all the widgets bug again and i need to remove the “CDATA”s manually to make them work.

Im beginner in coding, but any solution to keep wordpress from adding this would be highly appreciated.

Regards,
Quentin
