AWStats did not find any valid log lines that match your LogFormat parameter, in the 50th first non commented lines read of your log.
Your log file /var/log/httpd/cl-access must have a bad format or LogFormat parameter setup does not match this format.

Your AWStats LogFormat parameter is: 1
This means each line in your web server log file need to have "combined log format" like this:
111.22.33.44 - - [10/Jan/2001:02:14:14 +0200] "GET / HTTP/1.1" 200 1234 "http://www.fromserver.com/from.htm" "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)"

And this is an example of records AWStats found in your log file (the record number 50 in your log):
222.138.196.48 - - [30/Jun/2026:20:02:35 +0100] "-" 408 - "-" "-"


Setup ('/etc/awstats/awstats.cl.conf' file, web server or permissions) may be wrong.
Check config file, permissions and AWStats documentation (in 'docs' directory).
