I run MediaWiki 1.33 on Ubuntu with the latest version of PdfHandler, but thumbnails aren't being shown for PDFs. There's no obvious error being generated, the thumbnail images just don't appear. (Embedding a link like [[File:Sample.pdf|page=1|thumb|Test]]
produces only the text link with no image, and the file page itself shows only the generic PDF file type icon.)
I've verified I have all the necessary prerequisites:
- /usr/bin/gs
- /usr/bin/convert
- /usr/bin/pdfinfo
- /usr/bin/pdftotext
I've run the recommended maintenance scripts, but still no luck. I've also made sure it's appropriately configured in my LocalSettings.php — the settings are present and identical to the default settings. Does anyone have any ideas/suggestions as to what might be causing thumbnails not to appear? Any assistance would be much appreciated! Huwmanbeing (talk) 14:33, 7 September 2019 (UTC)
