Title: Include_path ERROR Last modified: August 19, 2016 --- # Include_path ERROR * [neotact](https://wordpress.org/support/users/neotact/) * (@neotact) * [15 years, 8 months ago](https://wordpress.org/support/topic/include_path-error/) * After “Successful Install” I receive the following error message when trying to log in: * > Fatal error: require_once() [function.require]: Failed opening required ‘./ > admin.php’ (include_path=’.;c:\PHP5′) in D:\Inetpub\neotact\blog\fam\wp-admin\ > index.php on line 10 * Admin.php is also in D:\Inetpub\neotact\blog\fam\wp-admin\ * How to fix? Is the INCLUDE_PATH being set improperly somewhere Viewing 5 replies - 1 through 5 (of 5 total) * [abumustafa](https://wordpress.org/support/users/abumustafa/) * (@abumustafa) * [15 years, 4 months ago](https://wordpress.org/support/topic/include_path-error/#post-1668315) * I get a similar problem after manually upgrading to WordPress 3.0.4 and going to domainname.com/wp-admin/ I get the following error: * `Fatal error: require_once() [function.require]: Failed opening required './wp- load.php' (include_path='.:/opt/local/lib/php') in ./admin.php on line 20` * So I did some more testing to find out the error is related to when a file is included using a ‘.’ path i.e. `require_once('./admin.php');` such as on line 10 of wp-admin/index.php. * If I rewrite this line as `require_once(dirname(__FILE__).'/admin.php');` we get past this error. But files all over WordPress are included like this and so this **IS NOT A WORK AROUND**. * **I need to _understand_ what could be the reason dirname() is not working when a file is included using a dot path such as ‘./admin.php’.** * Some tests inserted inside admin.php and called from wp-admin/index.php: test:` echo(__FILE__);` output: `./admin.php` * test: `echo(dirname(__FILE__));` output: `.` * test: `echo(dirname(dirname(__FILE__)));` output: `.` * But if I rewrite line 10 of wp-admin/index.php from `require_once('./admin.php');` to `require_once(dirname(__FILE__).'/admin.php');` and rerun the same tests inserted inside admin.php and called from wp-admin/index.php: test: `echo(__FILE__);` output: `/home/domainname.com/web/public/wp-admin/admin.php` * test: `echo(dirname(__FILE__));` output: `/home/domainname.com/web/public/wp- admin` * test: `echo(dirname(dirname(__FILE__)));` output: `/home/domainname.com/web/ public` * [esmi](https://wordpress.org/support/users/esmi/) * (@esmi) * [15 years, 4 months ago](https://wordpress.org/support/topic/include_path-error/#post-1668316) * Don’t edit core files! And try using the full path from document root for includes. * [abumustafa](https://wordpress.org/support/users/abumustafa/) * (@abumustafa) * [15 years, 4 months ago](https://wordpress.org/support/topic/include_path-error/#post-1668317) * Thanks esmi. This problem concerns core files which call includes without using a full path. I certainly do not want to edit them but they were recently rewritten by WordPress in a way which is causing problems in my environment. I’m guessing most servers are not having this problem with WordPress core files. * **Maybe someone can tell me what setting of PHP or Apache may be causing this strange behavior. **I run a Joyent SmartMachine with **root** access and the following details: * > System hostname somehost.joyent.us > Operating system Sun Solaris 11 Webmin > version 1.430 Virtualmin version 3.63.gpl (GPL) Theme version 6.3 Time on server > 11/Jan/2011 15:26 Kernel and CPU SunOS 5.11 on i86pc * > php -v > PHP 5.2.6 (cli) (built: Aug 5 2008 17:17:13) Copyright (c) 1997-2008 > The PHP Group Zend Engine v2.2.0, Copyright (c) 1998-2008 Zend Technologies * [velvetseas](https://wordpress.org/support/users/velvetseas/) * (@velvetseas) * [15 years, 3 months ago](https://wordpress.org/support/topic/include_path-error/#post-1668341) * Has anyone found a correction to this error?
