Hello. I ran into a problem with usermin today. Whenever I try to connect to any Account email (and the 3 domains I have) through the panel, I get the following error message.

Failed to save user : Failed to open PID file

I tried deleting the email and it didn’t fix it. Where can I find it?

@Jamie, I fixed it in Virtualmin here:
