I upgraded the Passbolt API to 2.13.5 on 18th Jan and I see the browser plugin was updated very recently.
I can see from the DB that the last user I created that successfully registered was on the 20th Jan. Which indicates that the problem started with the browser plugin update. Since then two different users have been unable to respond to the invite because the Plugin check during setup fails even after the plugin is installed. They have tried both Chrome and Firefox on Windows. I have also replicated the problem with Edge/Windows. The plugin is definitely installed and if I hit the root URL I get the message, “The plugin is installed but not configured”.
I raised a ticket "Get the plugin" does not recognise installed plugin after retry. Unable to sign up new users. · Issue #118 · passbolt/passbolt_browser_extension · GitHub but it was not reproducible and I (maybe mistakenly) closed the ticket because I believed it was an API issue due to the error message I was seeing in the logs.
I since created a temporary symlink to provide the missing file at the location it was looking for it and now I am not seeing any message in any JS console or server error log at all. So I guess that error message was an unrelated problem. I also tried re-clearing the API cache. I have tried enabling debug but there does not seem to be any new output in the API logs directory. All the files there are writable.
I updated the API from another version 2 to 2.13.5 using these instructions : Passbolt Help | Update passbolt server component (v2)
Health check is all-green (except for the Debug warning as I just enabled it).
In the absence of any console or debug/log output I would be grateful for any suggestions on how to resolve this. The only log messages I see expected authentication timeouts from users etc.
