.htaccess pcfg_openfile: unable to check htaccess file, ensure it is readable

If you are getting “(13)Permission denied: /home/username/public_html/shop/.htaccess pcfg_openfile: unable to check htaccess file, ensure it is readable, referer: http://www.yourdomain.com/shop/index.html” error in  apache error logs file /usr/local/apache/logs/error_log as well as the site is showing 403 Forbidden Error.

Then first please check the permissions of your folder and .htaccess file because folder permission are most likely 755 and .htaccess permission 644. Permissions can be changed via FTP or SSH.

In case you still are getting the same problem, then it might be the Frontpage Extensions causing the problem. To fix:

* Login into your CPanel account
* Click on Frontpage Extensions icon
* Click on Reinstall extensions button beside your problem domain.
* Done.

(make sure to have a backup copy of your data before reinstalling Frontpage)

And the site is showing “403 Forbidden Error”.
At first, I suspect it’s .htaccess problem, but actually it’s caused by Frontpage Extension.

To solve “.htaccess pcfg_openfile: unable to check htaccess file, ensure it is readable” follow the steps below:-

* Login into your CPanel account
* Click on “Frontpage Extensions” icon
* Click on “Reinstall extensions” button beside your problem domain.
*If you do not use any frontpage extensions, it’s good to uninstall this extension
* Done. The “.htaccess pcfg_openfile: unable to check htaccess file” problem has been fixed.

** If you are not on CPanel hosting, please contact your system administrator to fix the problem. ***
