Hi @christodhunter,
Glad you reached out. I’d like to start with a look at your system information. You can do this by navigating to Donations > Tools > System Info (tab) and click the button to “Get System Report” and copy/paste that in your reply here.
Are you using anything 3rd party to manage your slugs or permalinks?
Let me know if you have questions in the meantime, I’m happy to help.
Found the cause – nothing to do with GiveWP at all! Thanks so much for replying so quickly!
