Site seems to work. That said, this seems more of a Wordpress issue. Webmin/Virtualmin help you get a server up and running based on you OS choice. What the web developers do with it is another story.

I’m not saying none of this is a web server configuration issue but I do see a lot of things that are specific to WP. Short of an example of something not working on the site, kinda hard to say though.

Majority of them are bots looking to harvest links along with bots looking for routers to hack.
If you are using fail2ban? I can suggest you use the [apache-noscript] jail and set the maxretry to 1.
This blocks them for as long as you have fail2ban set for and cleans up the log a bit.

[apache-noscript]
enabled  = true
port     = http,https
logpath  = /var/log/virtualmin/*_error_log
maxretry = 1

You may also want to look into modsecurity. Just google search it…
