I used yum install apache and yum install php to install my packages. Therefore, I don't have a /usr/local/apache/htdocs folder. The web root is now /var/www/html, which originally I do have /usr/local/apache/htdocs that I configured during previous installations.

So the question is, does the error message say that it cannot change permissions on /usr/local/apache/htdocs/file_linux.php or /var/www/html/file_linux.php ? And does your PHP script have the correct path? The original problem may just have been that the /usr/local file system was mounted read-only after the power outage (perhaps due to some disk corruption caused by the failure?). Since then you have reinstalled apache, but possibly not in the place your PHP script expects it to be. That would be my first thing to check... This sounds really dumb, but it turned out that I have some inconsistencies going on in my httpd.conf file. Now I have changed both groups to daemon, and changed to owners as Rob suggested. Now it is finally working fine. Would I still need to change everything back to 0755? Or, should I ask, what is the appropriate permission I should be using here?
