Howdy,
While it's possible to experience issues when upgrading MySQL/MariaDB, that shouldn't be the issue you'd see. It shouldn't effect Virtualmin at all, since Virtualmin isn't using those for storing data.
Do you happen to see any errors being logged into /var/webmin/miniserv.error when that occurs?
-Eric
Thank you Eric... didn't know where the error logs were for webmin. I check them and here's what happens each time I hit refresh on the blank page of webmin (after login).
Warning: something's wrong at /usr/libexec/webmin/authentic-theme/authentic.pl line 8.Error: Failed to query Postfix config command to get the current value of parameter virtual_alias_maps:

Howdy,
Hmm, what is the output of these two commands:
which postconfpostconf -n
rpm -qa | grep postfix
Here's what I get for the which command. For postconf -n, I get "command not found" and no results for the rpm command.
[root@server ~]# which postconf/usr/bin/which: no postconf in (/root/perl5/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin)
Ah, I think that's the problem then. It sounds like Postfix isn't installed.
How did you initially perform the Virtualmin installation? Was that done with the install.sh script?
If so, Postfix should be installed.
If Virtualmin were installed manually though that could explain it.
But if the install.sh were used, it sounds like it was later removed... you may need to review your system to determine how it was removed, and whether other packages you require were removed as well.
You may want to make a backup of your /etc/postfix directory, and then try reinstalling Postfix though.

Oh no! I wonder what happened there? I did install Virtualmin through the install.sh script. I am really confused now because emails are still being sent although Postfix is not properly installed. I am using Postfix to send email via SMTP through SendGrid using these instructions: https://sendgrid.com/docs/Integrate/Mail_Servers/postfix.html
BUT here's where I'm confused... I don't have a /etc/postfix/main.cf file, instead it is /etc/postfix.main.cf.rpmsave.
I don't remember ever removing Postfix... the only thing I can remember removing recently was this when I decided to use php-mysql instead:
yum remove php-mysqlndSo what would be the proper way to install Postfix on CentOS 7? (I will be making backups of course.)
Well, let's try this... maybe somehow another program was installed into it's place.
What is the output of this command:
netstat -anlp | grep :25That will show what is listening on port 25, the email port.
-Eric
Hmmm take it back. I tried sending something on the server and apparently it isn't delivering mail after all. Also,
netstat -anlp | grep :25has no results.PROBLEM FIXED! So Postfix was not installed after all but I know it was at one point. No idea what happened. Anyway, here's what I did to get it back.
I followed the instructions here: https://www.virtualmin.com/node/36197#comment-144622
And then in CentOS 7 I did
yum install postfixand configured/etc/postfix/main.cfwith my needed SMTP settings and did a reboot of the server just to make sure everything was working good... could have also doneservice postfix restart.
