2) Click into the book of mormon, choose a random book, chapter
3) Try to change the language, it's been working flawlessly for weeks, as of this morning several languages are returning an error message.

I have verified this issue on Linux/brave and Linux/Chromium

How to bring this issue to the attention of the web admins so they can fix it?

I followed the steps mentioned and had no problem. It successfully changed from English to Spanish. The time difference (nearly 15 hours) between your post and mine appears to have been enough time for the issue to be corrected.
