First I did a test with the homepage of Jevelin that is in a envato [link], and threw the error is not they have been able to load 17 resources of the page.
I have also done it with several pages of my website and it throws the same error. There are resources that have not been able to be loaded by Google bots and that is a big problem for SEO.
Disable almost all my plugins, and everything remains the same.
What can I do to solve this problem?
