Thank you very much, Peter, for your answer.
Can this cause harm to the site’s navigation or clientele?
Thanks again

Or can I fix this?

It is not clear from the log entry whether the script in question is actually one that ought to exist or one that is needed for proper website operations. It could also be the case that a bad bot is trying to check on common scripts or security flaws. Another very common reason for the error are faulty rewrite rules in your .htaccess file. I have also seen shop systems where search engine friendly urls don't resolve/rewrite to the correct shop pages. It's not really easy to fix, because the name of the script is not mentioned in the error messages. You need to look at the access_log file to at the given time to get an idea what is happening, then follow the bread crumbs to find out why something is missing that is expected to be there.
