Does anyone know why searching on ask.libreoffice.org/ja/ fails?

Hi, I have a question regarding website infrastructure

searching for the term "LibreOffice" on
https://ask.libreoffice.org/ja/questions/
results in Internal server error

neither
Korean version
https://ask.libreoffice.org/ko/questions/
nor
Taiwanese version
https://ask.libreoffice.org/zh-tw/questions/
have this problem.

If this ML is not the right place to ask this type of question,
I would be happy if you let me know who to ask.
