No transactions possible

This morning I have been trying to sell some Hive-Engine tokens, and also tried to stake some...
But nothing works. It first seems all normal. You can put in your password and it all seems fine. But when it is broadcasted something doesn't goes through. I can't really put my finger on it, what exactly. But it seems to be happening only on the Hive blockchain, because Steem-Engine works perfectly. Buying, selling and staking all works like a charm there.

Anyone having the same issues?

Sincerely,
