Thumbnails not being auto-generated anymore

    8 years, 3 months ago

    Earlier thumbnails was auto-generated, but somewhere along the road (probably during an update in the recent 4-8 weeks) this plugin no longer generates thumbnails when an PDF is uploaded.

    Fancy – Use auto-generated document thumbnails – is checked.

    Allthough, we don’t have a Tumber.co-subscription, and both Ghostscript and Imagick is “not configured on server” (and not able to either, because shared hosting).

    There is no errors or warning in the log.

    My question is therefore – do you need one of the mentioned scripts to make thumbnail generation work – and if so, why did it work with earlier versions of the plugin/Wordpress? :o)

    Hi pmbs,

    Yes, in order to get thumbnails from PDFs, you would need at least one of the above-mentioned methods enabled — Ghostscript, ImageMagick, or a Thumber.co subscription. You wouldn’t get an error since DG is doing what is expected based on the thumbnail generation methods enabled.

    Regarding it having worked previously, I haven’t the foggiest how it could have worked ?? Nothing has changed in that regard other than additional methods of generation being added since the beginning of DG. The only thing I can think of is that your host changed something and while they previously had GS or IM available, they no longer have them available?

    Thanks for the quick reply. I guess there must be something server-related, because first when using the plugin I manually uploaded thumbnails until I discovered the “fancy” feature in settings.

    Then I just checked this feature, and for a couple of months thumbnails now have been auto-generated, until it recently stopped working.

    Guess I’ll check it out with the host then ??

    Actually I found out now that the server has Imagick installed:

    Path: /usr/local/bin/convert
Version return code is 127

    Version: ImageMagick 6.8.9-9 Q16 x86_64 2016-06-01 https://www.imagemagick.org
    Copyright: Copyright (C) 1999-2014 ImageMagick Studio LLC
    Features: DPC Modules OpenMP
    Delegates: bzlib cairo djvu fftw fontconfig freetype jbig jng jpeg lcms lqr ltdl lzma openexr pangocairo png rsvg tiff wmf x xml zlib

    The host said that the error might be because max_input_vars was exceeded – but I tried to raise it to 10 000 and still no changes:
    PHP Warning: Unknown: Input variables exceeded 1000. To increase the limit change max_input_vars in php.ini.

    Still says Your server is not configured to run Imagick. in the admin of the plugin, allthough I know this box was checked before even though it was in “disabled” mode.

    Anything you can help with? :<

    Never mind. Found out that the “Imagick”-class was missing, and that “ImageMagick” didn’t add this automatically. Host fixed it now!
