How To Install RedmineX Inline Edit
1. Go To Root & Unzip
Unzip the archive and upload the folder redminex-issue-list to redmine_root/plugins or upload the archive in the same location and perform the unzip command in the console. Do NOT change the plugin folder name.
2. Install Gems
From redmine_root run bundle install. No need for any migration (rake).
If the gems were installed correctly, this is roughly what you should see.

3. Restart
Restart Redmine. Based on your hosting provider / web server, you will need to run the following commands. Puma: sudo systemctl restart redmine.yourcompany.com.service or Passenger: touch tmp/restart.txt.
Do not forget to turn ON the Rest-api functionality in the administration section!
4. For Redmine 6.x+ Only
If you are using Redmine 6+, make sure the theme is present in redmine_root/themes/redminex_theme/.
Then:
Ensure correct permissions: chmod -R 755 redmine_root/themes/redminex_theme
Clear cache: rm -rf tmp/cache
Precompile assets (if you're in production mode): bundle exec rake assets:precompile RAILS_ENV=production
Restart Redmine
