Greetings, dear and beautiful Nomadic

I do not know if I'll help her, but, I already had this problem when using googlechrome to post. Then I went to the opera and did not make any more mistakes. I use pc.

Also, at the time you sign in, use your post key. Do not enter through steemconnect or give that error as well. If you are using steemconect to login, I imagine the error is this ...

Hope it helped you or someone else help.

Good afternoon!
