Cancel this! My apologies. Something went wrong with the upload of the files and the files were not actually saving in the directory. Looks like a server permissions glitch or something. Anyway….this is RESOLVED.

Can someone please have a look at this? it is ruining my users’ mobile experience. Thanks in advance…. 🙂

….unless you have tweaked the caps and roles so much that people who aren’t admins have manage_options for other reasons……lol 🙂

Thanks so much, that’s very helpful. Now I know where to look for the solution.

Hi @shahriar, I really need to get this taken care of as soon as possible. I have people waiting to update resources, and we are stuck. Thanks!

Hi Timothy,

Which problem are you having? Did you resolve it? This thread morphed into more than one issue, so it’s a bit confusing. Ultimately I used handcrafted screenshots as thumbnails instead of the generated PDFs. And the javascript problem…I honestly can’t remember where that ended up. If that was your issue, and you haven’t sorted it out, let me know and I’ll try to dig a little deeper.

I am server support. 🙂

I have ImageMagick 6 installed. This is the policy.xml file. I don’t see anything like what you suggested – no domain called “modules”. Am I in the wrong place? (This is in my /etc/ImageMagick-6 dir) Or do I need to add that line? (or update to v7?)

Unfortunately I cannot — we don’t allow regular FTP and setting up credentials for external users is not a trivial exercise. However, I can execute any changes you would suggest. I just changed that folder to 777 (it was 755) and it didn’t change the result. Is there something else I can try?

OK, I am trying to work with [pdf_thumb] but it’s giving me a broken image. Imagick is installed.

http://dev.nrocnetwork.org/resources/courses/nroc-math-2-2/ — go to the bottom of the page, before the footer. (you can click on the X in the popup box to get rid of it)

For testing purposes, the template contains nothing but the [pdf_thumb] shortcode

Thank you. This is all helpful, as we may go with our own generated images. But one last stab at letting WPDM do the heavy lifting as we had intended it to do….

Does WPDM have the quality setting defined in the code for ImageMagick PNGs, as per the following link?

http://www.imagemagick.org/Usage/thumbnails/#formats

This setting seems to be something specified on the fly in the script, not something I can just “set” in a config file. Thoughts?

This is a reasonable workaround, but if the true problem is indeed that filtering is not working, then I would like some assurance that will be addressed as a bug fix if WPDM is not filtering correctly. It has always filtered just fine in the past, so something has changed that is causing the problem.

There is no [pdf_thumb] listed in the template variables, so I was using [thumb_WxH] — how is this different?

What do you mean by “use a higher resolution”? Are you referring to the PDF file itself? Or a setting….where would I set that?

If we decide to upload a special high res thumbnail of our own, what template variable would be used to pull the “featured image” (assuming that’s the best method)?

Ah, yes that was it! Thank you.
