Wish I could help more; recommend making sure your PDF is 1.4 or older and trying other (uncompressed, perhaps) files. * I will unlikely be able to reply to this for a few weeks. * Thread Starter [Alundra](https://wordpress.org/support/users/alundra/) * (@alundra) * [10 years, 2 months ago](https://wordpress.org/support/topic/uncaught-exception-3/#post-7215034) * All of my PDFs are the same, it wouldn’t make sense for them to work with some files and not others :(. * Thread Starter [Alundra](https://wordpress.org/support/users/alundra/) * (@alundra) * [10 years, 1 month ago](https://wordpress.org/support/topic/uncaught-exception-3/#post-7215083) * I’d really love some help when you get back :). * Plugin Author [Little Package](https://wordpress.org/support/users/littlepackage/) * (@littlepackage) * [10 years ago](https://wordpress.org/support/topic/uncaught-exception-3/#post-7215104) * Hi [@alundra](https://wordpress.org/support/users/alundra/), * Can you please send example(s) of PDFs which work, and PDFs which DO NOT work to [hello@waterwoo.me](https://wordpress.org/support/topic/uncaught-exception-3/hello@waterwoo.me?output_format=md)? I will be happy to help. * Thank you, Caroline * Thread Starter [Alundra](https://wordpress.org/support/users/alundra/) * (@alundra) * [10 years ago](https://wordpress.org/support/topic/uncaught-exception-3/#post-7215105) * Hi Caroline 🙂 * Unfortunately I didn’t record which ones didn’t or did work with confidence, so I hope perhaps this can help: * 1. I would create linework in Illustrator, rasterise it (through the edit menu) and save as high quality print preset on exporting as PDF, but with editing capabilities turned off. 2. I would open said PDF in Acrobat (latest version) and click organise pages, then insert from file and add another PDF I had made in InDesign as a back page to this linework. 3. I’d save and upload. It seems to me the simpler designs were okay but the bigger ones would have issues. Perhaps it had to do with filesize? * I had to be very careful when saving and resave some because they were 1.5 or 1.7 (can’t recall exactly) so perhaps that was the reason. * The woocommerce plugin has a popup if there’s an issue on the product page and tells anyone trying to download the file “can’t be served at this time”. I think if you did that it would help a whole lot :D. * Plugin Author [Little Package](https://wordpress.org/support/users/littlepackage/) * (@littlepackage) * [10 years ago](https://wordpress.org/support/topic/uncaught-exception-3/#post-7215106) * Hi there, * It has tons to do with file size. If you’re on basic hosting with limited bandwidth and PHP memory limits and timeouts set low, it’s not going to be able to process large files. Of course I don’t know anything about your hosting, but for many people this is the issue. * I will be working more on error handling ASAP. I know it’s a big problem. * I hope this helps! Thank you, Caroline * Thread Starter [Alundra](https://wordpress.org/support/users/alundra/) * (@alundra) * [10 years ago](https://wordpress.org/support/topic/uncaught-exception-3/#post-7215107) * That’s great news Caroline! * I’m on a dedicated server, no issues yet with the uploads or downloads so I think I may be okay. If the script was running out of time or something I think I would have caught it in a log somewhere but unsure. If you could maybe show an alert that the file is quite large and will take time/resources to process that may help too. * Good luck, I hope you guys get it sorted :D.
