BLT Popups WP Registry grade A. No security issues foundWP RegistryNo security issues foundOpen the reportA

Lightweight, single-purpose image popups for WordPress — scheduled, targeted, and cache-safe. One popup is live site-wide at a time; unlimited popups can be saved for reuse.

Part of the BLT family of plugins by S-FX.com.

Features

• Single custom post type (blt_popup); each popup is a reusable post.
• Only one popup live at a time — a quick toggle switch on the popup list (backed by WordPress's native Publish/Draft status) activates one and deactivates any other.
• Modal lightbox with configurable overlay dimming (color + opacity).
• Close via the "×", click-outside, or the Esc key; focus-trapped for keyboard users.
• Scheduling by date range and daily time window (site timezone).
• Targeting: all pages, homepage only, specific pages, specific post types, or URL pattern (contains / starts-with).
• Frequency capping: every load, once per session, once per day, once every N days, or once ever.
• WordPress Media Library image picker; optional call-to-action button.
• Cache-safe by design: eligibility is resolved through an uncached REST endpoint, so a popup with an elapsed end date never lingers on cached HTML (Cloudflare "cache everything" friendly).
• In-admin live preview plus a nonce-gated front-end preview URL.
• Lightweight impression/click counters (admins excluded).
• No jQuery, no page-builder dependency, no build step.

Installation

1. Install the zip from Plugins → Add New → Upload Plugin, or copy the blt-popups folder to wp-content/plugins/.
2. Activate the plugin.
3. Go to BLT Popups → Add New, configure the image, destination, schedule, targeting, and frequency, then click Publish to make it live — or flip the toggle on any saved popup from the All Popups list.

Automatic updates

Updates are delivered from this repository's GitHub Releases via the bundled plugin-update-checker. While the repository is public no credentials are needed; for a private repository, define BLT_POPUPS_GITHUB_TOKEN in wp-config.php — or, on a site running two or more BLT plugins, store the token once on the shared BLT screen and enable it for BLT Popups there. The wp-config constant always wins.

Under the shared BLT update policy the automatic check runs at most once a day, anchored to midnight site time. Manual checks always run immediately: the Check for Updates link on the Plugins row, Check again on Dashboard → Updates, and the Check for Updates action on the BLT Popups list screen.

Releases

Every push to main runs .github/workflows/release.yml, which publishes a GitHub Release with an installable blt-popups-<version>.zip. The current version in blt-popups.php is released as-is if it has no release yet; otherwise the patch version is bumped automatically (use #minor or #major in a commit message to bump higher).
