Error in Combination with facets module.

Check latest version

Automatically closed - issue fixed for 2 weeks with no activity.

This error is still there for me. The problem is something like this: https://drupal.stackexchange.com/questions/195545/custom-language-switch...

Same for me. I installed the module and added a block (with a BS dropdown style) normally. When I visit the front page I get the exception.

drupal 10.3.6
advanced_language_selector 1.5.0
facets 2.0.9
