    WP Thumbnail Preview Issue, by c.note

    WP is no longer creating thumbnail previews of PDF uploads for me. I’ve successfully used this feature as a method of displaying the PDF front-cover on various websites so its affects the front-end of the sites. Fortunately I have a check for an image or display a placeholder if no thumb was found which prevented a blank space but the front-cover was way more intuitive for the user than any placeholder.

    I checked various sites on my local environment as well two distinct hosting environments all of which were previously creating thumbnails. All sites were running 4.9.4 but no thumbs are now created for a PDF upload.

    I understand this was introduced in WP 4.7 and I’ve previously had no issues with it.

    Does it now require to be enabled?
