Sometimes ??? Can you be more specific how page will display content when there is none?
Anyway, your advice was pointed out in very first comment. 
I am still researching this like Stan advised, but I noticed some thing in Microsoft Edge only (not in Chrome) when I refresh homepage first part of content appears and then adfter that dissappear and remains blank, what is it ? Why is so if all is blank ?
This is called cross-browser optimisation You can learn about this term on online as this phenomenon is well described and it will waste of time writing about it here.
Simply said you have to investigate what is causing this issue and search why this happens in specific browser, how to fix it or go around. I believe there will be a simple solution in your case as WF solve most of it.
Welcome to web development. 
I have found ⊠backup!!! LOL
Take a look in read only link, all content is here and sections are ⊠EMPTY
As you can see it now looks a bit different so it was some mess with divs or something other, just letting you know!!!
I will be more carefull now, too bad it doesnât allow usual hard coding within those collections
what page @seolinker ?
your homepage have content and template âscrollingsectionâ is still empty.
Take a look here, all is showing after publishing correct backup, please explain if you want
hi @seolinker Im already tired to repeat the same solution all over again. Please click on your links you have published that had issues rendering content.
These still do not show any content. I believe that you miss-understanding whole principle. IMHO finishing courses on WFU can bring some light to your confusion.
Good luck
