always show 300 second cool down

Thanks for creating the plugin and the effort!

I have just installed it on my blog. However it always show the message “Please be reminded that there is a 5 minute cooldown when creating a Steem post in the Steem blockchain.” Although I have waited for a long time between tries.

I have reconfigured the plugin settings and verified the account name and private key. It still shows the same…. Please help!!
