I tried changing the settings in Polylang to remove language prefix in the URL and everything is working now.
However, may I know if I wish to have ‘zh’ in the URL as prefix then how do I approach to solve the issue? I believe the issue is caused by the language prefix which bbPress does not recognize it by default.
Just to update on my research regards to my issue.
I noticed that during the search process it is looking for a term_id which belongs to the English language. I also noticed that the search URL is always without the language identifier, I am suspecting that without the language identifier the search function could not search for the correct set of data.
Does anyone know how to add language identifier into the search URL?
My URL for Chinese language is having the prefix ‘zh’.
