 * Hello
    When I want to generate a pdf I get 500 Internal Server Error / blank 
   page. I already modified the memory limit to 256MB, but I still have that problem.
   In the WooCommerce state it detects the increase in memory, but not in the status
   of the plugin. Can you help me? Thank you

 * Hi! I’m sorry to hear you’re having issues.
    We have a sticky post here in the
   forums that should help you find the error behind the 500 error: [https://wordpress.org/support/topic/500-internal-server-error-blank-page/](https://wordpress.org/support/topic/500-internal-server-error-blank-page/)
 * Which version of PDF invoices are you using? WooCommerce shows only the PHP memory
   limit, but the PDF invoice plugin checks the WP Memory limit too – it depends
   on your server configuration which is leading, but both are actually shown in
   the Status page since 2.0.11.
 * Let me know what you find!

 * Hi,
    I had te same problem. If you using w3 total cache, make sure you disable
   Object Cache under General settings. This solves my problem.

 * Hi [@hutamanama](https://wordpress.org/support/users/hutamanama/) thanks for 
   sharing this information with us! We were not aware of any specific W3 Total 
   Cache incompatibilities, but this can be partly setup specific too. Good to know
   either way! 🙂
