GoAccess "Token 'host.somedomain.tld' doesn't match specifier '%h'"

Just a short post if someone else stumbles about this.

I use GoAccess to view my Apache logfiles on the command line. Now I got an error which I never encountered before.

Token 'host.somedomain.tld' doesn't match specifier '%h'

Strange. I use the standard CustomLog format line from Apache. Also known as " NCSA Combined Log Format". Which is what I choose in GoAccess to open the logfile.

Long story short: If you run an older version there is a bug in GoAccess. If the first line in the logfile doesn't start with an IPv4 or IPv6 you will get the error above.

I got the error with version 1.4, updated to 1.7 and the error was gone. Most likely just a bad regular expression.
