I've just installed it on the latest version of WP (4.9). I get this error I've seen other people are having:
Please be reminded that there is a 5 minute cooldown when creating a Steem post in the Steem blockchain.
300 seconds left to do another post action.
I'm trying to repost my older posts first, I haven't tried with a new post. Is this a compatibility issue with 4.9?
It didn't work for me too :(
same problem here
