Hello all. I attempted an upgrade to 2026-03a on the day it released.
The upgrade was done exactly at 2026-03-13_20_25_02 according to the git commit on my side.
However, when I did that upgrade, all email service worked except for webmail. After login, webmail would only show a blank white page with the text “email”, tested on multiple browsers and computers.
At that time, I rolled back as I did not have time to solve the issues.
I just tried again upgrading to 2026-03b shortly before making this post, and the symptoms are exactly the same. Dovecot works, email flows, webmail does not work.
Additional details:
The webpage DOES have content in the received HTML. Just nothing visible:
Additionally, it appears as if most of the script resources are failing due to 404’s.
Any ideas what could be wrong with my setup?
