I had a similar problem. i was trying to change my profile pictures, and couldnt access the page. I tried everything, including signing into my wallet and steemit profile at the same time. After I selected "remain signed in", I was able to access the page and upload my new profile pictures and was also allowed to post again. One issue I have now, is in 2018, I recieved nearly 13,000 dogecoin, which were basically worthless at the time. The Dogecoin was stored on "Blocktrades", but when I asked Blocktrades how to access the Dogecoin, they said it wasnt there. When Steemit first came on line, it was based in Luxembourg, but was later sold, to some other group. I have a Poloniex accout before, but now since Im American, I cannot use Poloniex, even though it is still based in Delaware. I also do not understand this "Hive" system they have implemented. I had a list of freinds, but lost contact with everyone after the "Hive" thing came out. Any explanation or information will be greatly appreciated. Try logging on both the wallet and Steemit account at the same time and select "Stay logged in" Hope this helps, Marco
