Are you running a Mastodon server where the locale files have been damaged such that "toot" was accidentally replaced with "post"? I wrote a script at https://github.com/freeradical-dot-zone/mastools/blob/main/src/mastools/scripts/fix_locale.py to fix it. Download that, then run:

$ uv run fix_locale.py -w app/javascript/mastodon/locales/en.json
$ uv run fix_locale.py -w config/locales/en.yml

to correct the problem.
