WP Thumbnail Preview Issue

    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?

    here is a very detailed write up on that subject. Maybe after reading you can better determine what has happened in preventing this from working on your site.

    Ah thank you.

    I had upgraded the version of my MAMP Pro in recent times and Imagick/ImageMagick was no longer enabled. I was certain it enabled by default as I don’t ever recalling manually enabling it in the past.

    That explains the local environment so hopefully I can get answers from the hosting company.

    Its a very useful feature to have a front-cover thumbnail auto-generated.

    Hosting company needed to update the relevant modules, took them a while to figure it out at first they pointed the finger at recent theme developments but I could see from the media library roughly when it stopped working so that didn’t fit with the theme development updates timeline, so it was server issue.

    Can’t believe it stopped working both locally and remotely at roughly the same time. I was initially stumped by this.
