I got it yesterday while trying to make a post. It wouldn't allow me to post and that red error kept popping up.

I copied my post, refreshed the page and then re-submitted my post. And it worked.

I just got it when trying to vote in the March Madness poll, having made 32 selections. Wish I could copy/refresh/paste that!

However, worked fine after a refresh, just had to remember who I voted for!

I see this message from time to time. Usually a browser refresh or open and close will resolve.

I have been looking into this last week. This is often caused by a session timeout or IP address switch (I.e. browsing Pinside while on a train or in a car). But normally, you should get auto logged on via a session cookie. Without even noticing it.

Do you guys maybe have some aggressive cookie settings or possibly an ad blocker or other browser extension that might be causing this? A long shot but maybe we can figure out the cause of this.

Not me, and it only happened out of the blue the one time, knock on silicon!

Just browsing at home on my tablet.

I only get the error when trying to edit a post, as soon as I try to save it. All posts, all areas. Using my note 10 phone. Closing browser does not resolve.
