Was able to log in since site opened.
Today, for the first time, I cannot. I get a popup error message, "Your client is too old; please Ctr-Reload the page to get a new one."
Okay, I pressed Ctr and moved my cursor over the reload icon. (Most recent Firefox, on Windows 10). Same message. Closed down Firefox and opened it again. Same problem. Obviously, I do not have any problems accessing this (Forum) side of the ShuffleIt website.
What's the solution? Firefox is my only available browser.
[UPDATE: Got the solution from the Discord site. Ignore the incorrect info on the popup window. Instead, hit Ctr-R, to reload. That immediately solved the issue.
There was a thread today on Discord, from other users with the same issue. Apparently, there was a new release/update today, and that's why all of our clients were too old.]
