Strange language bug

I have multilanguage site and sometimes very strange things happen.
When I open main page website menu is partly in current language and partly in english (default language). Also some text blocks on the site is in English instead of current language.
After page reload - everything is ok. Some visitors report about the same situation. It happens very occasionally. But 2-3 times per day.

What can I try to find a problem? I don’t use any caching plugins etc.

Could you please provide some more information?

  • Your Kirby version
  • Your environment (server, PHP version, server side caching)
  • Is Kirby’s page caching enabled in your config?
  • 3.7.1
  • litespeed, php 7.4.30
  • return [
    ‘debug’ => true,
    ‘kirbytext.image.figure’ => false,
    ‘languages’ => true,
    ‘languages.detect’ => false,
    ‘date.handler’ => ‘strftime’

Does this only happen on the remote server or also in your local environment?
