Hi Hei,
It could happen on any host, in fact, most popular hosts implement security and firewall. That makes their hosting environment more preferable and trustworthy among others. What I’m saying is, please check it with your hosting to get more information what and why some of the resources are being blocked. Wordpress and theme has no capability to monitor what’s being blocked, I love to see and find what’s really going on but unfortunately I can’t without any information.
And yes, it’s always the same resources I retried it over and over. The only difference is when you checked it and once I checked it so I’m not sure what resources you were seeing. But what I confirm is, it’s mobile friendly on my view as per screenshot.
It’s not a loading issue since it loads on a standard browser, both desktop, and mobile. It’s not just loading on google bot (crawler), please check this https://support.google.com/webmasters/answer/6352293#blocked-resources (it’s from Learn More button on the mobile friendly test)
The resource wasn’t loadable in a reasonable amount of time. In this case, try running the test again. If it continues to happen, consider hosting the resource somewhere else, or else try to discover and fix the reason for lack of response from the host.
Not the case, it loads fast on desktop and mobile (actual devices)
The resource does not exist in the location listed (404 error). Fix the resource URL.
It’s loading on desktop and mobile without 404, I used browser developer tools to check it.
The resource is inaccessible to non-logged-in users. The test accesses the page as an anonymous user; ensure that all resources are accessible to anonymous users.
It’s accessible to non-logged in users, as you havent provided any login at all when I checked it.
The resource is blocked to Googlebot by a robots.txt file. If the resource is important (see below), if it is on your own site, you might want to unblock the resource to Googlebot; if it is on another site, you might want to contact the site’s webmaster and ask to have it unblocked.
Now, this is up to you and I can’t confirm it since I have no access to your site.
And our demos have robots.txt that blocks google bot because it doesn’t need to be indexed, its main purpose is just a demo.
It’s intentional on our demo’s environment, but it’s not part of the demo and it shouldn’t be carried on anyone’s site once the demo is imported. The demo only contains data, images, and no files are imported to Wordpress root path (where robots.txt is present), nor to theme folders.
And google console has its own tool for robots.txt, like here
You can utilize the tools and check it on your site.
And about this site, https://www.grooow.io/x-theme-examples/. Please check the resources,
You’ll see that the resources are coming from minified files, which is generated by cache plugin and they aren’t loaded by google bot (skipped). And it’s completely different from your site (comparison of the resources).
Again, please contact your hosting provider to get more information about this. It’s not just the theme resources are being blocked from your site, but also the resources that are built to Wordpress itself.
Thanks!
