 * I’m trying to install WordPress, but when I open the install.php file in my browser,
   I get the following error:
 * Warning: main(ABSPATH/wp-admin/admin-functions.php): failed to open stream: No
   such file or directory in /home/sites/site30/web/blog/wp-admin/upgrade-functions.
   php on line 3
 * Fatal error: main(): Failed opening required ‘ABSPATH/wp-admin/admin-functions.
   php’ (include_path=’.:/usr/local/lib/php’) in /home/sites/site30/web/blog/wp-
   admin/upgrade-functions.php on line 3
 * I’m not sure what to do to fix this problem, if there’s an error in the database
   information I gave or what.

 * Errors about missing files when trying to run the install means there was an 
   incomplete, incorrect or corrupted upload of the files. I’d suggest deleting 
   them from your server and re-upload, making sure to keep the file structure (
   i.e. files in their appropriate directories) intact.
