In checking my web server error log messages there seem to be a plethora of the following "client denied by server configuration: public_html/data/dont-panic-if-you-see-this-in-your-logs-it-means-your-directory-permissions-are-correct.png" . . .
I'm not panicking - I assume that the system is checking to see if the directory permissions are (still) set up properly - but is it really necessary to check this so many times? In my case multiple times a day? I wouldn't expect the permissions to change, in fact I never change them.
Is there a way to set this check to a lower level - say once per day?
