Thanks for your quickly response!
In fact, that URL looks okay to me, too. As the homepage. But, please, can you check other posts like:
And other posts that you can access in this pages above. I changed the menu itens to make easly access other posts and pages with and without problems (please take a look in them)
Note, for example, that have visual differences if compare:
Which is stranger, because they are same post type, with no reason to be visually different.
I suspected that could be a browser cache, but I've clean up everything, and tested in differents PCs – I tried a new browser too, recent installed with no cache. In all instances, I have same problem.
If you want, you can dehactive and activated my plugins, or create a new post, a new “produto” (product) – this website still are in develoment and only us have access. After that, compare the fonts and backgrounds showed.
I noticed that the missing styles (when ASP are active) are set in Avada config panel – not in style.css from my theme. That could be a clue?
