How to update your plugins:
- Backup production
- Test updates first in a staging environment. To make a copy you can use a plugin like Snapshot to back up your site and install it on your local host. Otherwise most hosting companies provide the tools for staging site creation.
- Update plugins in production
Alternatives to manual updates include auto updates. Check with your host provider. For example, WPEngine offers Smart Plugin Manager to automatically update all plugins and ensure they are working as expected. In the event there is an issue, it will automatically revert and restore your site to its previous state.
