I receive the following error message when signing out of the Community Forums on both Windows 8.1 and Windows 10, in both Firefox 57 on Windows 8.1/ 10, and Microsoft Edge on Windows 10.
Thank you for bringing this to our attention. I was also able to replicate this. I will pass it along to have it addressed as soon as possible.
Thank you for your participation in the Forums!
