Hi!
We had a bunch of forum malfuntions today (your can read more about it in this post:
https://permies.com/t/101408/GLITCH-PEOPLE-UNABLE-POST) Could you post a direct link to the post you're talking about?
(If you right-click the little page icon that's to the left of the date stamp on the post and "copy link address", you can save the URL of that post.)
We don't have any records of thumbs-up that I know of, but I can try to look at the post and test the thumbs-up on it.
