Why am I getting include() and require() errors from one directory of my site and not another?

Total newbie here, so take it as you will...

I'm doing a site upgrade right now, and everything works fine except...

I have a WordPress installation in a subdirectory, and now that I've brought the main site live, I'm getting

include(/settings.php) [function.include]: failed to open stream: No such file or directory

and

includ开发者_C百科e() [function.include]: Failed opening '/settings.php' for inclusion (include_path='.:')

on includes from within the subdirectory. I've played with setting different include_path settings, I know for sure the files are there (they are being included with no problems from the root directory), and I'm changed no permissions or anything during the rollout of the site.

Please let me know if this question is improper, or misplaced, or too vague, or what have you - first post after months of googling and lurking.

thanks in advance!

You're likely using php in a chrooted environment, so the root path of the server doesnt match that of the script.

Regarding the variables scope issue, could you post some sample code?

"/settings.php" points to the root of your server. It should be "settings.php" if it is on the same path and it should be in quotes.

Cheers

I would recommend adding define('WP_DEBUG', true); to your wp-config.php file and report back with more information. Make sure to undo this any you grab the info for debugging as having this on a live site could be a security risk. I just search my whole WP directory for include( "/settings.php" ); and could not find anything, which makes me think that it make be an issue with a plugin, theme, or other custom code. You could troubleshoot this by disabling all of your plugins, seeing if the site works again, and then painstakingly enabling your plugins individually until you find the culprit.

Does the error message you get point to a specific file and line number? That can help debug the problem.
