This section describes how to install the plugin and get it working.
- Activate the plugin through the ‘Plugins’ menu in WordPress
- Start using the plugin by creating widgets or inserting QR Codes to blog posts
- What is QR Code?
QR Code is well described on Wikipedia.
- How does the plugin work?
Plugin generates a QR Code image using Esponce API 3.0.
Image is then downloaded and cached so all images are served from a local server.
- Why is my QR Code not displayed?
- A parameter may have wrong value, check parameters, especially ‘size’ and colors.
- Shortcode: syntax may not be valid, try to use UI editor.
- Plugin is out of date, try to update to the latest version.
- Esponce.com is in maintenance mode or API (web service) blocks connections.
- There could be other issues, e.g. bugs or browser/platform issues.
- How to use shortcode?

- A feature is not working as expected. What can I do?
There are some settings you can change. Open esp-qrcode.php in editor (or edit plugin code in WordPress) and change PHP constants:
- ESPONCE_PERMALINK_WITH_QUERY – a value indicating whether to include URL query in permalink: true to add query strings (default value), false for no query strings (smaller QR code)
- ESPONCE_ENABLE_CACHING – enable image caching: true to save generated QR Code image on local server (more reliable), false to always generate new image from web service (frequent content changes)
