Hello, We have a discourse for the Scala PL for users which was running fine for years : [imagen] Scala Users a forum for the Scala programming language. beginner questions welcome Last week, I upgraded to the latest version using "./launcher rebuild app "…

Looking deeper, deleting the _t cookie remove the “error 500”, but the error appears again when logged after maybe around 1h.

v2026.9.0 has not been release yet - are you referring to the development/latest version? [imagen] Discourse Releases Browse Discourse release history & changelogs.

I’ve not set any specific version, so I guess by default it should be latest (according to "tests-passed" is now "latest" ). In the dashboard, this is the version I get at the bottom.

In /logs, can you find the 500 error and share the error and its backtrace?
