I need a Discourse specialist to bring my forum up to the latest stable release and clear the bugs that appeared during recent update attempts. The main troublemakers are a few third-party plugins; they must be cleanly removed so the core can update and run error-free. Scope (keep it lean and focused): • Remove the specified third-party plugins from the codebase and any remaining hooks. • Run the standard Discourse upgrade process (via launcher or SSH) and confirm the site boots without errors. • Verify basic functions—log-in, posting, search and notifications—work as expected after the update. Please be comfortable with Ruby on Rails, Ember.js, the Discourse CLI, and typical Docker-based deployments. I will provide server access. If you have tackled similar plugin-related update issues before, let me know—speed and precision are important here.
