Trouble with Reorder Ultimate and Double-Check

Reorder Ultimate Error Message:

Whenever I try to submit an answer, the review page reloads.
In the case of Double-Check, I need to press the Enter button multiple times before changing to the next question, sometimes the page reloads.

the answer is in the very thread you linked:

You’ll need to enable script compatibility mode for it to continue working (WaniKani > Settings > App > Compatibility Mode).

The WK team recently made a breaking change to the API, and this particular script will probably never be updated to work outside of compatibility mode, although a few people are working on making new scripts to cover the same functionality.

Thanks! I wonder what happened, I had been using Reorder Ultimate without problem until yesterday.
