Header causing problems with site

Hello – I have same problem as what another user had posted about in this link: https://www.ads-software.com/support/topic/footer-doesnt-switch-with-switching-of-the-language/

@creative365 – what was your resolution??

Here is summary of the situation: I am using Polylang with Elementor Pro to show my site (https://www.asiarainbowride.com) in two languages, EN and CN. I created a header template in Elementor in EN. I published and then all appeared to be expected. However, at some point during the evening, I tried to edit my EN homepage with Elementor and it would only show the header template, not the homepage content which I had previously created. I also found that when I went to the header template, it showed nothing. The strange thing is that the published live version of the site is still showing the header and page content as expected.

More details: -At some point, I also was receiving error message “content area not found” when I tried to edit the homepage. However, later it resolved and went back to showing just the header content (and no page content).

So now I am stuck unable to edit my homepage, and my header template in Elementor is behaving very strangely (sometimes showing in one language and sometimes in another, whenever I go into edit with Elementor).

Any help much appreciated!
