Getting Logged Out of ClassicPress

Since migrating several blogs from WordPress to ClassicPress, I get logged out whenever I follow a link to my dashboard from the custom start page on my LAN. Or from any other website.

It remembers me when I…

• Type in the admin URL directly
• Open a bookmark
• Open it from Vivaldi Speed Dial
• Follow a link from the blog front-end
• Follow a link from anywhere else on the same site.

Only following a link from outside logs me out.

A little digging turned this up: ClassicPress uses the SameSite=Strict mode for admin cookies. This is a way to mitigate cross-site attacks by telling the browser it shouldn’t send the cookies if the request is coming from another site.

That’s a good thing! And it explains exactly what I’m seeing.

So at least it makes sense, even though it does mean I need to change my workflow a bit.
