I suspect it's a browser cache issue of some sort.
It's odd. In private mode in my browser with another user, it all works fine. But in regular mode I have this issue. I just tried flushing cache and files in Firefox but it did not help.
Wish you would work to help solve the problem instead of making this a competition.
I'd love to know WHICH cache is causing this. Same issue in both Firefox AND Chrome. Deactivating WP Rocket, bypassing Cloudflare, and deactivating Redis, none of it helped. Which cache is left?
Nope, tested some more. Acting weird even in private mode. Doesn't help to deactivate all caching. Definitely some sort of bug.
In private mode, I click "like", and it likes. I remove my like and it says "X liked and reacted" which is just weird. I click like again and it only says "You liked" without mention of other who have liked. It only shows when I refresh the page.
If it's claimed to be a cache issue, I wonder which cache is in play since I deactivated forum cache, tried deactivating Redis and WP Foro and bypassing CF. No other cache.
