I am still having the same issue and have been trying since this afternoon. I just tried again right now to submit my profile and got the same error message. It also seems the system will not save the profile past the title and overview point. Thank You.
I am a new member on your website. However, I already have some troubles useing it. I tried to fill my profile twiced, and each time the website stop working on specific period of time. So, I needed to close your web and login one more time, after what it shows me that I need to fill the form again, all the steps that did before just disepires. However, I tried to fill the profile third time, although, the problem with the website happend again. The website just stop answering. However, on this time, I had an opportunity to fill in & save all the profile steps, the only thing I needed to do was put my profile photo. It was the last thing I needed to do but the website stop answering, and now when I refresh the page it shows e again that before using it I need to fill in the profile. It disappointed because I spent two and half hours to fill the profile with all it problems, and now I again where I started.
I'm sorry for the inconvenience this has caused you. Could you please share if there is an error that is showing on your end when you try to save your profile information?
