Frequently Asked Questions

Common questions about Simple Lightbox for WordPress

Plugin is filtering the content of posts and pages and appends lightbox effect for native Gutenberg-Blocks: Image, Gallery, Media-and-Text, Featured Image, Video and Youtube-Video. It also works for external images or YT-videos that are not on your site.

It filters the content of the page, post etc (setting: postTypes). Meaning exactly the content that WP stores in the database as content for posts, pages etc. (Using the_content filter) All elements in html figure tags and img tags will be filtered and if its CSS-Class is defined in the plugin-settings.json (setting: cssClassesToSearch).

Maybe, see preconditions above. If your theme provides output that is NOT stored as content in the database it will not work. If your media ( be it image or video ) is not given in a figure tag it will not work. Positive feedback is reported from Beaver Builder, Post Types of Advanced Custom Fields. Negative feedback is given by GeneratePress that generates page content in special elements by the theme files. So, just try if it works and mind the preconditions.

The settings are stored in a separate file called plugin-settings.json, located in the main plugin folder. In this file, you can: * postTypes – Define which post or page types or other should include the lightbox. * hrefTypes – Choose which link type may already be present on the image (Empty, Media). * cssClassesToSearch – Specify CSS classes used for images or videos to apply the lightbox. Mind: These are defined in the figure-Tag above the img-tag! Predefined classes are: "wp-block-image", "wp-block-post-featured-image", "wp-block-embed-youtube", "wp-block-media-text__media", "wp-block-video" Not working with : "wp-block-cover" * excludeIDs – List post or page WordPress-IDs that should not include a lightbox. * rewriteScope – Select where HTML rendering takes place: * '' - Empty Value: Default or standard setting to render the content only. * body – Render in PHP for the entire page. * javascript – Render on the client side for the entire script. Default settings are optimized for most use cases, so you usually don’t need to change them initially.

Yes, you may buy the fslightbox.js an add the file fslightbox.js to the folder ./folder-where-the-plugin-is-installed/js/fslightbox-paid. That's it.

No. You can use this plugin with pure WordPress with Gutenberg editor enabled. But mind the preconditions above.

Yes. Lightbox is fully responsive - it scales to every device.

No. Plugin just uses fslightbox.js. Free or paid version optionally.

Yes, the Update to 2.0.0 implements a backup / restore logic for plugin-settings.json and the files in ./js/fslightbox-paid. This will work ONLY for all future updates because the php-files have to be on your server already. So, with this update it is the last time you have to save your files in advance. The process creates the folder ../simple-lightbox-fslight-backup in you Plugin-Directory which won't be deleted after Update. If you want the backup-restore process running with the Update to V2.0.0 you have to manually copy the files simple-lightbox-fslight.php and ./admin/pre-post-install.php from Github via ftp to your server. The backup / restore logic won't work if you install the Plugin manually as zip-File.

Yes, there are errors shown like "The service worker navigation preload request was cancelled before 'preloadResponse' settled. If you intend to use 'preloadResponse', use waitUntil() or respondWith() to wait for the promise to settle". This issue is not solvable by me. If you dislike it: Just delete the JS-File simple-lightbox.min.js. The Video Sync will no longer work after that.
