Apache httpd allows the use of distributed configuration files (usually called .htaccess) that control the configuration for different parts of the filesystem. When configured to use these configuration files, httpd must check for them in each directory along the path to the requested file. If it cannot check for any reasons, it must deny access to avoid revealing content that should be protected by an unreadable .htaccess file.
The above error message indicates that httpd is unable to check whether an .htaccess file exists or valid permissions for that account folders.
Check your httpd to stop looking for .htaccess files by setting AllowOverride off in httpd.conf for the relevant directories.
Please check the permissions of your folder and .htaccess file because folder permission are most likely 755 and .htaccess permission 644 . To change permissions use chmod 644 after that still you are getting same problem,then might be Frontpage Extension problem.
* Login into your CPanel account
* Click on Frontpage Extensions icon
* Click on Reinstall extensions button beside your problem domain.
Most cases .htaccess pcfg_openfile: unable to check htaccess file, ensure it is readable error will be fixed.
