    I uploaded a bunch of pdf files (about 50 of them), and now see
    the following error rendered on my page – any ideas what I can do to fix this:

    Hi Bigsipper,

    It sounds like Ghostscript doesn’t understand one or more of the PDFs you are using. I’ve heard of this happening occasionally with some weird formats.

    One thing I would suggest that may resolve the issue is upgrading your version of Ghostscript. Based on the stack trace you provided, it looks like you are running 8.70 which was released in ’09 and it’s possible it will have issues with newer derivations of the PDF format. That said, I cannot guarantee that will resolve the problem.

    On my end, I need to figure out why you are having that error dump displayed. That shouldn’t be making it onto the frontend.

    Can you run a quick test for me? I would like to see if we can get anything useful from the DG logging.

    1. Go to Dashboard -> Settings -> Document Gallery -> Advanced and enable logging.
    2. Go to the Thumbnail Management tab, select all of the generated thumbnails and delete them.
    3. Go to your gallery and reproduce the problem you described above.
    4. Go to Dashboard -> Settings -> Document Gallery -> Logging and see if there are any Error or Warning logs (you can filter this in the top right of the log screen). If there is anything recent in there, paste those errors/warnings here.

    EDIT: Also, as a short-term fix, you can disable the Ghostscript generation method which should prevent the errors you’re seeing. You’ll likely get the default PDF icons (unless Google Drive is active), so not an ideal long-term fix.

    EDIT 2: Can you tell me what PHP version you are currently running?

    Update:

    I’ve found the issue that’s resulting in you getting the big stacktrace in the gallery output and the fix will be implemented in the next release (hopefully some time today). This won’t change the fact that generating thumbnails for the PDFs that are currently failing. For that, I still recommend updating Ghostscript since you are using a version that is about 5 years old (a century in software terms).

    Update 2:

    If you update to version 2.3.1 (just released), the error stack trace you’re seeing should no longer be displayed.
