When I refresh the page it loads with some other fonts and color for a moment and then back to a normal design. Kindly look at the attachment where you can see red mark section which I am seeing for 1 to 2 second when I refresh the page. You can also check this by refreshing the given URL of my website. You will get an idea what I am talking about.
When I tried to refresh your theme URL https://jnews.io/yoga/, it loads perfectly without seeing any other kinds of fonts or color. It loads as it is configured.
I have also provided the URL of one of the post’s cache version, in which you can see that Google is caching some other kind of design instead of the one I have set. Kindly compare the live version and cache version. Both are totally different.
Regarding this issue, i think this is related with cache issue. You may need to try to disable it for a while and see if there’s any different. Also, may i know what kind of cache system that you use on your website?
