Hi Arnoud,
Glad you reached out. Happy to help!
I’ve not seen an issue with deleting Forms, Donations, or Donors. Here’s a screencast of me attempting to do replicate: https://www.loom.com/share/7056174cbf234090b9c8247aa666eceb?sid=388898e7-a596-4390-a739-1fdc22a169c0
Are there any JavaScript console errors before and/or after trying to delete? Here’s how to check for JavaScript console errors. In Chrome, Microsoft Edge, and Safari you can use the following:
– Windows/Linux: Press Control + Shift + J
– Mac: Press Command + Option + J
For Firefox you can use:
– Windows/Linux: Press Control + Shift + K
– Mac: Press Command + Option + K
GiveWP also has documentation on this here: https://givewp.com/documentation/resources/how-to-open-the-developers-console-in-your-web-browser/
As a workaround, can you try using Legacy View to delete? The button to switch is at the top right-hand corner of the list of Donations/Donors/Forms.
Let me know about the above and we’ll keep digging into this should the issue persist. Have a good day!
