Language Not Automatically Switching on Thrive Theme Site

Hello everyone,

I’m reaching out regarding an issue I’ve been experiencing with the Polylang plugin on my WordPress site, which is built with the Thrive Theme. Previously, the language on my site would automatically switch based on the user’s browser language preference. However, recently, this functionality seems to have stopped working, and visitors are no longer redirected to the correct language version of the homepage.

Here are some details about my setup:

Permalinks Settings:
Selected Setting 2 (https://la-casetta-marche.com/en/my-post/), Hide URL Information for default Language, remove /language/ from permalinks.

Static Front Page: Yes, I’m using a static front page.
Polylang Settings: Language Detection activated, No Synchronization
Link to my site: https://la-casetta-marche.com/
What I’ve Tried: I’ve experimented with various settings in polylang, including toggling the automatic language detection feature on and off, but without success. There is no kind of cache activated.
Conflicts: There doesn’t seem to be any conflict with other themes or plugins, as the issue persists even with all other plugins deactivated.

I’m hoping to get some assistance in resolving this issue. If anyone has experienced a similar problem or has any insights into what might be causing this issue, I would greatly appreciate your help.

Thank you in advance for your assistance.
