#### Troubleshooting Plugin Conflicts

A plugin conflict happens when:

* A plugin update breaks the website.
* A new plugin causes errors with existing plugins or themes.
* Certain features stop working after an update.

**How to Identify a Plugin Conflict:**

* **Check Error Messages**: Look for error logs or messages in your CMS dashboard.
* **Deactivate Plugins One by One**: Disable each plugin to see which one causes the issue.
* **Enable Debug Mode**: Use debugging tools to pinpoint conflicts.
* **Check for JavaScript Errors**: Use browser developer tools (F12 > Console) to look for script errors.
* **Switch to a Default Theme**: See if the issue is theme-related.

**Pro Tip**: Use a staging site to test plugins before updating on a live website.

1. **Step 1**: Go to **Plugins/Extensions/Modules Manager**.
2. **Step 2**: Deactivate the plugin and check if the issue resolves.
