Flipcause has informed me that the issue some donors have seen with expired sessions is happening when using their integrated pages rather than their hosted pages.

For our purposes, if you go to the Donations page here at dlang.org and select one of the campaigns in the menu presented there, or click the "Donate Now" button and select a campaign from the menu that pops up there, you'll be using the integrated page and may see the session expired error.

They are working to resolve the issue and have asked me to direct folks to the hosted pages instead of the integrated ones. I'm posting the direct links to the here as a temporary measure, but will have a more permanent solution in place in as soon as I can make time for it. (Note that the campaign link on the DConf registration page goes to the hosted page and not an integrated page, so should be okay for everyone, but I'm adding the link here anyway since it's also available in the campaign menu.)

==> Your session has expired !
:-(

Now a timer is displayed, but I only got this result, even before reaching the page for
the payment details (credit card info).

Please other forum users test it, to know, if it is caused by something else...
...just donate 1 Dollar if you want to help.

Okay, it just happened for me, too. I've reported it. I'd still like to know if it's happening for everyone in the donation campaigns or if it's just certain people from certain locations. We've had some DConf registrations that went through okay, but I've seen no new donations in the other campaigns recently.

I tried as well. It happened to me, too.

Thanks. I got an email from them today informing letting me know the issue is their top priority at the moment. Fingers crossed they solve it soon.

I can report that they've discovered the problem and hope to have it fixed in the next two or three days.
