BookFrame Help
Before you post, name the plugin and describe the screen you are on. If a license is involved, say whether Plus is active. Do not paste a license key into a public forum. You can send a private note through the contact form instead.
Work from the WordPress admin screens named on this page. Save after each change so you can tell which setting caused the result. If you use a shortcode or a widget, include that shortcode or the widget name in your question. Say what you expected to see and what the screen showed instead.
Help for this plugin is the WordPress.org support forum plus the contact form. There is no separate support site. Questions about a grandslambert.com account or checkout belong with the company terms, not in a thread about a display setting. Use the contact form when the note should stay private. This help page does not replace the plugin privacy policy or the terms of use. When you write, repeat the steps you already tried, including the settings screen and any shortcode or widget, so the next reply can start from that point.
Settings and import
Open Books → Settings to choose Google Books or Open Library, save a Google Books API key, and set permalinks. Search and import from Add New Book. Existing books keep the source they were imported from. Visitors do not run those searches.
Google Books sends the search text, a title or an ISBN, to https://www.googleapis.com/books/v1/volumes. The API key goes in a request header, and the User-Agent includes your site URL. Open Library needs no key. A search or import sends the title, ISBN, or author name to https://openlibrary.org/, and the User-Agent includes your site URL. Cover images may load from https://covers.openlibrary.org/.
Books, authors, and the fallback templates work without Elementor. Elementor adds the book widgets. You can publish the library either way. Saved books stay in your WordPress database.
BookFrame Plus
Get Plus downloads the add-on from a license key, then asks you to activate it. Downloading Plus does not activate it. Reading list, read status, and visitor ratings need BookFrame Plus and an active license. Enter the key under Books → Settings → Plus. Those tools are for logged-in users. Guests cannot save a list or leave a 1 to 10 rating.
