I’ve just realized that my homepage is loading a blank page in stead of the content.
That happens on mobile browsers (I’ve checked it with 2 different devices, both with Chrome and Opera), and that only happens on the homepage and some subpages (not all). On PC seems it work fine.
I’ve been looking for the solution on WP forums, and it seems to be something between the new 5.1 WP version and the theme:
Thank you for your quick reply.
For now I’ll keep the 5.0.3 version installed because I have not much time, but I’ll try again some weeks later to update plugins and WP, just to check if the problem was about WP, PHP version or some plugin.
