Hello.
I'm having problems in a freshly installed iredmail. The only thing I've done after the installation is installing my own certificates, that seems to be ok.
When I try to add a new user, I get an "internal server error".
No errors in nginx, dovecot, postfix and system logs.
Not working when the script create_mail_user_SQL.sh is used (no errors and no user created in the DB). However, if I use the commands shown by the script, I can add the user in the DB.
I'm not planning to add many users in the future, but I would like to fix it.
Any suggestions?
Thanks for your attention.

**** SOLVED ****
I've tried again in a new server, using the 1.3.1 release (previously I have cloned it from the git repository) and now it's working. Maybe some problem with the dev version.
