Export from V12 to V13 Header display issue 
Автор: Steve J.I exported a v12 project to v13 and all works fine in responsive mode but the header jumbles up on mobile phone view. I have read that v13 renders differently.....but how to I get this part of the website to display correctly without building a whole new website. I have experimented with taking the header content out and then re-entering but same issue. Do i have to build a new template ? or header , if so how can i do this without ruining my existing website. I currently have uploaded an older version (ftp files only) so that at least I have a website. in the version that i have uploaded (v12) the header completely goes blank when viewed on a mobile. Very difficult to find a tutorial on this - Can anyone please help me. URL www.sonbouapartments.com
In the preview you will see on top 4 colour bars, these are the responsive viewports.
In v12 there was only 1 setting for these in v13 you can adjust every viewport and choose what you want on each of them.
Keep in mind the colours and adjust your screen to them. Then set the template header options in x5 correct for every colour, in x5 you will see the colours on the left side.
if these are all set to your likings then all should be ok.
Myron made a viideo, i am not sure what exactly is there but it will surely help I gues. https://helpcenter.websitex5.com/ru/post/176688
