Gutenberg doesn't work with WP Multilang

[Slaver]

Posts are not saved after installing Gutenberg 3.3.0 on site with WP Multilang 2.2.5. I've checked it on empty site after installation WordPress 4.9.7

I tested my plugin with last version Gutenberg and all are working fine.

I've made the screencast for displaying the problem https://drive.google.com/file/d/1MFttDYW-rdeXhBwQwtTTEtNv4aGfq91Z/view Everything works without Gutenberg

WP 4.9.7, Gutenberg 3.4.0, WP Multilang 2.2.6

Thanks for screencast. Did You try reload page in admin? Does the text changes exist? Or the problem only on front side?

You are right VaLeXaR. Just tested and it works perfectly. :)

[Slaver]

Thanks! It's very interesting. Maybe I have some problems with my test server. I'll try to debug

[Slaver]

The problem happend only when option 'Use prefix for language by default' is activated.

[VaLeXaR]

Only on Your server? Or You tested this bug on a test server?

[Slaver]

It seems that only on my server. I've tested on two virtual machines with different versions of Ubuntu and Nginx/PHP-FPM. Maybe I've some problems with routes. For example, when I try to preview post I get Too Many Redirects (WP_DEBUG=true).

I had this same issue. Thank you @Slaver for the hint.
