Today I was doing small changes (which I already did before) on my server: edited the my.cnf for some more query cache and edited fcgid.conf to raise max fcgid processes a bit. After changing the files I did restart mysql through the webinterface which worked well. Also I restarted Apache through the interface but it did not wan't to start. I ran the command to see the 'log' and it could not fine /home/DOMAINNAME/public_html. So I looked for the directory and it was gone, but I found the directory with the name '25' in my home. It was the directory that used to be the directory for that virtual server with domainname as name. I changed 25 back to DOMAINNAME and started Apache. It worked again!
But now I am wondering: any clue what happened and possibly could create this problem? Could there anything be wrong? It seems to work well again, but I really would like to know what could be the reason that the directory name of this virtual server got renamed to a number.
Centos 7. Virtualmin/Webmin latest version.
