ABSPATH problem

This WordPress site I’m working on works fine, but there’s one image uploading tool in the dashboard that the previous person taking care of it created/installed that I get this error message where it’s interface should be. This happened when we moved the site. I don’t know anything about the image uploading thing but I assume the error message is generic will speak for itself:

Warning: require_once(./wp-settings.php) [function.require-once]: failed to open stream: No such file or directory in /home1/worldcl7/public_html/blog/wp-config.php on line 80

Fatal error: require_once() [function.require]: Failed opening required ‘./wp-settings.php’ (include_path=’.:/usr/lib64/php’) in /home1/worldcl7/public_html/blog/wp-config.php on line 80

Line 80 being the “require_once(ABSPATH . ‘wp-settings.php’);” line. The other lines pertaining to ABSPATH might be relevant so:

/** Absolute path to the WordPress directory. */
if ( !defined(‘ABSPATH’) )
define(‘ABSPATH’, dirname(‘__FILE__’) . ‘/’);

/** Sets up WordPress vars and included files. */
require_once(ABSPATH . ‘wp-settings.php’);

Any idea what the issue is? There’s really nothing wrong with any other part of the site, only this one thing seems to take issue with ABSPATH.
