Helpful tip - if you get the transaction broadcast error message, check to make sure there was an actual error. Sometimes, it fires as a false positive.
I just joined steemit (hi all!), made my first post (https://steemit.com/web/@kleingtm/how-much-do-websites-cost) and had the same issue.
It turns out, the post actually HAD gone out to the blockchain, but the code must not have handled the response correctly.
Hey Tom!
This does happen sometimes; if you get the error, check your
blogpage to make sure it didn't actually go through.If your post did not get any votes or comments yet, you can always click the
deletebutton. Of course, your post's history will still be publicly available on the blockchain, but it won't appear viewable on Steemit or on your blog page.Thanks for the info!
