 **Q: What can I do if my builds fail suddenly from a broken plugin release or plugin dependency?**
 
-A: Check out the plugin's [releases](https://github.com/netlify/netlify-plugin-nextjs/releases). You can manually install `npm install -D @netlify/[email protected]` at the last working version.
-Once a new working release is out, you can uninstall the plugin at this locked version (`npm uninstall -D @netlify/plugin-nextjs`), which will re-enable Netlify's build system to use the latest plugin version by default.
