Title: Duplicate payment ID bug? Last modified: March 22, 2017 --- # Duplicate payment ID bug? * Resolved [Tijmen Smit](https://wordpress.org/support/users/tijmensmit/) * (@tijmensmit) * [10 years ago](https://wordpress.org/support/topic/duplicate-payment-id-bug/) * I just noticed that the last two payments that where processed on my site have the same payment ID on the Payment History page. * I’m using 2.5.13, but the changelog for 2.5.15 says nothing about payment ids, so not sure if using the latest version would have prevented this from happening * Also not sure this is caused by EDD in the first place, maybe more a possible issue with WP itself that it allows duplicate ids to exist? * Let me know if you want more information about my installation, or the exact time that both order where made. * [https://wordpress.org/plugins/easy-digital-downloads/](https://wordpress.org/plugins/easy-digital-downloads/) Viewing 3 replies - 1 through 3 (of 3 total) * Moderator [Pippin Williamson](https://wordpress.org/support/users/mordauk/) * (@mordauk) * [10 years ago](https://wordpress.org/support/topic/duplicate-payment-id-bug/#post-7374050) * Hi Tijmen, * Do you use sequential order numbers? * Could you go to Downloads > Tools > System Info and post the contents here? * Thread Starter [Tijmen Smit](https://wordpress.org/support/users/tijmensmit/) * (@tijmensmit) * [10 years ago](https://wordpress.org/support/topic/duplicate-payment-id-bug/#post-7374116) * I do use sequential order numbers.
