Hello, Thorsten!
Thank you for a prompt reply!
The problem is SOLVED now.
Description of the solution:
I deleted the whole WordPress installation and started over again from scratch, performing all setup steps one after another to figure out where redirection stops functioning.
I installed WordPress in multisite subdomain mode, created another site on ‘ru.’ subdomain, installed MultilingualPress plugin and chose languages (with their priorities equal to 10) and relationships between my two websites. So far everything worked Ok.
The problem appears during theme customization, right after I set up ‘Static Front Page’ parameter of my theme to a dedicated page named ‘Home’. The theme is ParallaxSome made by AccessPress Themes, to be clear.
To achieve desired behaviour (redirection of visitors to appropriate language frontpage) I went to ‘Pages > Home > Edit > Change relationship’ of my main site, chose ‘Select existing post’ radio button and unambiguously stated relationship to home page of another my site (named ‘home’ in my case).
So, the plugin had been working correctly all the time, yet some setup was needed ??
To stay consistent, below are answers to the questions you asked.
Yes, exactly right – I’m using a default WordPress .htaccess file for multisite subdomain installation. Later I figured out that my web hosting provider added a few lines to it for more convenient access to cPanel via my domain name, but those lines doesn’t interfere with ‘HTTP Redirect’ function of MultilingualPress.

I assume by “doesn’t work” you mean no matter what browser (settings) you are visiting the site with, you always end up at the URL that you initially requested, right?
Your assumption is totally correct ??
I enabled WordPress functions ‘WP_DEBUG’ and ‘WP_DEBUG_LOG’ in my wp-congig.php to see any issues overall, but debug.log remains empty.
I did not set up any sort of server-side caching, so, I suppose, it’s disabled.
With your permission, I’ll just leave this long-read with hope that it may help someone struggling against same trouble.
Kind regards,
Ruslan
