Please follow these steps:
- Go to WPML -> Languages -> Edit languages -> Make sure the chinese language has the URL encoded
- Re-save the permalinks
- Flush any cache memory that might exist
- Double-check if the issue has disappeared
Can you tell me the results of the steps described above?
I'm more than happy to help you solve this issue 🙂
1.- Please share a URL where the issue can be seen and that we can use as a reference.
2.- Share the access credentials to the site in your next message, which I have set private. This will allow me to reproduce the issue in the URL shared on the previous point and double-check the WPML configuration.
