the weird thing is, this account is my account for my shop, but my main account and the main account of my coowner can log in to marketplace with no problems. It's really weird
I have had the same problem for 2 days now. I can log in to SL, I can login to my page and the SL community, but I can't login to Marketplace. I either get the message that the username and password are incorrect, or I come back to the start page, without being logged in. Very frustrating.
