# C3 CloudFront Cache Controller
## The C3 CloudFront Cache Controller is a plugin designed to invalidate (clear) AWS CloudFront caches. It's particularly useful for users of Amimoto Managed Hosting or self-hosted environments utilizing AWS CloudFront.
**Plugin Name:** C3 CloudFront Cache Controller
**Plugin Directory:** [https://ja.wordpress.org/plugins/c3-cloudfront-clear-cache/](https://ja.wordpress.org/plugins/c3-cloudfront-clear-cache/)
**Description:** This plugin facilitates the invalidation of AWS CloudFront caches. For those using Amimoto Managed Hosting or self-hosted setups with AWS CloudFront, activating this plugin ensures seamless cache management within WordPress.
**Configuration Details:**
- **Managed Hosting:**
- No configuration is required. Ensure the plugin is updated as needed.
- **Self-Hosting:**
- You'll need AWS Access and Secret Keys associated with an IAM role that has invalidation permissions on CloudFront (e.g., CloudFrontFullAccess).
- Keep the plugin updated as necessary.
**Important Notes:**
- **General:**
- This plugin utilizes the AWS SDK.
- If other active plugins are using an older version of the AWS SDK, **C3 CloudFront Clear Cache** might not function correctly. WordPress loads plugins alphabetically; thus, if a plugin loading an older AWS SDK precedes C3, it can cause errors during C3's operations, preventing cache invalidation.
- To resolve such conflicts, consider deactivating plugins that use the AWS SDK. Notably, using the **BackWPUp** plugin alongside **C3 CloudFront Clear Cache** has been known to cause issues.
- Please contact the respective plugin developers for updates regarding the AWS SDK version within each plugin.
- **Managed Hosting:**
- If errors occur with this plugin active alongside **AMIMOTO Dashboard** or **CF Preview Fix**, try deactivating these plugins to identify the source of the issue.
- Check `/var/log/www-error.log` for any errors unrelated to this plugin and address them as needed.
- **Self-Hosting:**
- Similar to managed hosting, if errors arise with **AMIMOTO Dashboard** or **CF Preview Fix** active, consider deactivating them to troubleshoot.
- Review `/var/log/www-error.log` for other potential errors and take appropriate action.
