Everything you need to manage
your Lightsail CDN cache
Three ways to clear cache — whichever fits your workflow.
Auto-Clear on Publish
Fires a full CDN invalidation automatically whenever a post or page is published or updated. Choose exactly which post types trigger the clear — including custom post types.
Scheduled Cache Clearing
Set up recurring cache clears on a fixed interval (every 5 minutes to 24 hours), on specific days of the week, or on specific dates each month. Uses your WordPress timezone.
Live Countdown Timer
When scheduling is active, a live countdown timer shows exactly how long until the next cache clear — with the precise date and time displayed alongside it.
Secure wp-config.php Credentials
AWS credentials are defined as constants in wp-config.php — never stored in the database. The access key is masked in the admin UI after entry. All API calls use AWS Signature Version 4.
Status Dashboard
At-a-glance status panel showing your AWS connection state, auto-clear toggle, active schedule mode, and the last time cache was successfully cleared.
Test Connection
Verify your AWS access key, secret key, and Lightsail distribution name with one click — calls the read-only Lightsail API and never touches your cache, so you know it's working before you rely on it.
Setup
Up and running
in three steps
No SDK. No AWS Console after setup. Just four constants and you're done.
Install & Activate
Search for Lightsail CDN Cache Manager in the WordPress plugin directory, install, and activate. Or download the ZIP from WordPress.org and upload manually.
Add Credentials to wp-config.php
Add four constants to wp-config.php: your AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_DEFAULT_REGION, and LIGHTSAIL_DISTRIBUTION_NAME.
Manage Your Cache
Go to Settings → Lightsail Manager. Clear cache manually, enable auto-clear for specific post types, or configure a recurring schedule — all from one tab-based admin panel.
What AWS permissions does my IAM user need?
Your IAM user needs two Lightsail actions: lightsail:GetDistributions and lightsail:ResetDistributionCache. Create a custom IAM policy with only these two actions for minimal permissions.
Where are my AWS credentials stored?
Credentials are defined as PHP constants in wp-config.php — they are never written to the database. The admin panel displays only the last four characters of the access key for verification. All API calls go directly from your server to AWS; nothing passes through ByteCore Stack servers.
Does this work with my Lightsail CDN distribution?
Yes. The plugin uses the ResetDistributionCache API action, which is the standard way to invalidate a Lightsail CDN distribution. You need an active Lightsail distribution and its exact distribution name from the AWS Lightsail console under Networking → CDN distributions.
Does this work with CloudFront?
No. This plugin is built specifically for AWS Lightsail CDN distributions. CloudFront uses a different API. A separate BCS CloudFront Manager is on the roadmap for Q4 2026.
Can I schedule cache clears at specific times?
Yes. The Schedule tab offers three modes: Interval (every 5 minutes to 24 hours), Weekly (specific days of the week at a set time), and Monthly (specific dates each month at a set time). All times use your WordPress timezone setting. A live countdown timer shows when the next clear will run.
Will auto-clear fire on every save, including autosaves?
No. Auto-clear only fires when a post reaches publish status. WordPress autosaves and draft saves are ignored. Media attachments are also excluded regardless of your post type selection.
How do I know if my AWS credentials are set up correctly?
Use the Test Connection button on the Configuration tab. It calls the read-only lightsail:GetDistributions action to verify your access key, secret key, and distribution name — without clearing your cache — and tells you exactly what's wrong if something fails.
Will this be free?
Yes — always. Lightsail CDN Cache Manager is 100% free and GPL v2 licensed, with no paid tier, no feature gating, and no upsell — consistent with all other ByteCore Stack plugins.
