[Solved] Bad displaying with posts composed with divi builder

Hi, I have a web with Divi theme, which uses a visual builder with modules to create and edit the posts. I asked about this before at the pre-sale quetions forum  and Astighk answer me:

I don’t think it will have any effect on content in wpForo version. The small CSS conflict can be easily sovled.

So I've purchased the plugin and, as I feared, the post in the forum shows a lot of shortcodes and no image. 

• Article example: https://www.deviolines.com/resinas-un-asunto-pegajoso/
• Forum version:  https://www.deviolines.com/forum/articulos-de-la-web/resinas-un-asunto-pegajoso/#post-4882

Any idea how to fix thix?

If there's no solution, is it posible to recovery the moneyy?

Thanks
