Show me error when I try to dowload the pdf file

Hi @zaoyao,

Could you check the WooCommerce logs to see if there are errors with the wpo-wcpdf or fatal-errors prefix? If so, please share the logs with us. You’ll find the logs under WooCommerce > Status > Logs. See Where to find error logs

Also, go to WooCommerce > Status > System Status, click on Get system report, then click on Copy for support, paste it on https://pastebin.com/ (set a paste expiration for one week, just in case), and finally paste the pastebin.com link in your reply here.

Kindly check

Thanks for providing more details, @zaoyao.

After checking your system report and WooCommerce logs, I realized of these situations:

• You have activated another plugin with a similar name to ours, but developed by a different company (Acowebs). Please deactivate that plugin, to rule out that this is causing a conflict with ours, and try to open a PDF document, to check if it opens correctly.
• You have several logs with critical errors related with an allowed memory size limit. It is likely that your server limit is under the values displayed on your system report. If after following my recommendation of the first point, the document still generates an error 500, try contacting at your hosting provider.
