When I applied multiple port participation changes to a VLAN, I received several dialog boxes warning me of tagged/untagged issues. The last dialog asked if I wanted to see these repeated messages (or something close to that). I clicked NO.
From that point on, no changes to VLANs are applied (Pressing Apply has no effect). Hard and soft factory resets did not resolve this issue.

@HP Support: If you have not seen this issue before please open a ticket. This switch needs to be back in working order yesterday.
