Interesting. I've had this issue a few weeks ago but I didn't have redactor installed either. I have no idea what I did to fix it, and the others couldn't reproduce. I'll have to wait until it crops up again, but the fact that a plugin might have interfered is a good hint, thanks!
SOLVED Potential Issue with GPRD - only admin is allowed to DL data
I am running 1.9.3 synced to master.
When a user (but admin) is trying to dl his personal posts etc on GPRD page, the browser switches to an empty page that has:
Chrome (inspect, network): shows the following error:
Status Code: 403 Forbidden
Referrer Policy: strict-origin-when-cross-origin
Any idea how to resolve?
We will release 1.9.4 with this fix hopefully this week.
