Multi-Page .PDFs into Media Library – breaking

Hi,

I’ve been trying to sleuth out why this particular WordPress website is having trouble uploading .PDF files that are more than one page. It’s not a particularly big file – it’s 203Kb; 3 pages long.

On other WP sites I’ve built, even using the exact same template and same version of WP, I have no trouble at all with this exact file. But this current site won’t load it and I’m stumped as to the cause.

However, the school site I’m building has a “new” version (that I’m building) and an old version that we will be replacing. Both exist on the same platform, and I suspect that it’s a server or issue with the host.

Before I go back to the host and start blindly trying to troubleshoot, I thought I’d ask on here if anyone else has experienced this and what the solution was?

I’m not getting an HTTP error; the file ‘appears’ to load, but I’m getting a weird, broken one-page image rather than the full .PDF file. I CAN load single page .PDF files, but not multi-page ones. I thought perhaps it was the .PDF file itself, and re-generated an optimized version of it; but the original file works fine on OTHER WP sites that use different hosts.

Ideas? I’m well and truly puzzled.
