Which release are you on? Stable, Beta or tests-passed?

[תמונה] Stephen: passed stable When go to discourse web it shows me : discourse v2.3.6

Looks like @gerhard fixed this 10 days ago, there were some 6.0 migrations which caused issues with stable. [תמונה] Stable release v2.3.6 upgrade bumpiness due to plugin Support I fixed the migrations in FIX: Make migrations work with Discourse stable · discourse/discourse-policy@94635bf · GitHub. I hope there was nothing else in the last couple of commits that breaks on the stable branch. Run a: git pull ./launcher rebuild app Or if you renamed your app.yml as myapp.yml ./launcher rebuild myapp Then try again- report back if it doesn’t work.

I fixed the migration in the akismet plugin. Please give it a try by rebuilding your app. https://github.com/discourse/discourse-akismet/commit/d2503ae65f79e250940590ffb1536d8ec5ef38e5
