pfSense

can't replicate, will leave for further feedback

Create a functional OVPN with two users. (with OpenVPN Client Export Utility Pack)
Delete than the users.
If you delete the "last" user you are not able to login via Webinterface. (sse pic.)
It crash.

We need a full copy of your config.xml to work with. We cannot replicate this in any circumstances that we have tried, there must be something specific to your config that is leading to this problem.

Well the key here is that you're using a username that is all numbers, apparently. Not sure how well that was tested, it's certainly not something that is common to see. I had thought we rejected those even.

If you make a user with the username "004" and then delete it, somehow the /conf/ symlink is removed as well as some files in /etc/ (like resolv.conf at least)

Needs more investigation, but as a workaround, don't use numerical usernames.
