"Please re-edit this profile block, and submit it again!" is happening again upon updating the link.
I'm having the same problem :/
(I'm using firefox 55.0.3 on a windows 10 laptop btw if it matters)
Encountering this issue as well. Using Chrome Version 61.0.3163.100 (Official Build) (64-bit). Though I'm not sure it has anything to do with browsers at this point in time. Any insight on what may be causing the fuss or ?
Mine's broken as well. Firefox - Mac OS

July group!
Mine is too. The videos I have there was previously are working, but I get that error when I try to add a new one.

Having the same issue on both laptop and phone. I thought it was just me! I keep getting "Please re-edit this profile block, and submit it again!" Second time I've been having profile issues.

I didn't know there was a problem until I tried to edit the title of my Multimedia block. Now it's broken, and putting in proper Height and Width numbers doesn't fix it either. :/
Are you still having issues with this?
I just went to my profile and tried editing that section again to check and it's working now for me :D so it finally appears to be fixed!
It's been working again for me as well.. since I've been using it for nearly a month after randomly testing it and discovering it. I'm regretting not remembering that I posted to this thread so that I could've come back and said something way earlier. 😓 Thanks for the help/notification <3
