Are you have problems on Hive?
I tried to comment on my own post on Hive.blog and got this error message:
Transaction broadcast error: Obsolete form of transaction detected, update your wallet.
How do you fix it?
I did change my node and that can fix the problem like it did some hours ago. But then I wasn't able to post a few minutes ago. So, I restarted my Firefox web browser on my laptop computer and refreshed the cache and that may have did the trick and now I can post comments and posts as far as I know but I cannot say that did was what fixed the problem absolutely or not.
I had the same issue. Your post helped me out. Thanks @joeyarnoldvn.
Great
