I upgraded to 25.7 on release day. Seems to have largely gone smoothly.

However, yesterday, I started getting the titular CSRF error. I've tried clearing just the site cookies, rebooting my client machine, and using other browsers, neither of which had previously accessed my OPNsense GUI. Nothing has worked, including completely deleting all cookies, site data, etc. on one of the other browsers.

I haven't yet tried rebooting the OPNsense box, as I'll have to schedule some downtime.

Is there any remedy short of rebooting the box? Will this work?

Thanks in advance for any advice.

Follow up: I rebooted OPNsense and found that the disk was filled (due to the regression reported in #48085.15). I cleaned up the disk and reverted to the latest 25.1 snapshot and all now seems well.
