Fatal Error – Line 14

I’ve enlisted a computer programmer friend to help me with my blog crash, but even he’s presently unable to fix. Any advice would be appreciated by he and I. He helped me write the following summary:

In attempting to fix a problem with strange characters appearing as described here, I took the advice to remove

define(‘DB_CHARSET’, ‘utf8’);

from the wp-config.php file. That, however, caused even more trouble (probably because there are a number of posts using Asian characters).

When I went to repair the damage, though, things got further out of control, leading to a problem where I get the following error:

Fatal error: Call to undefined function: wp() in /home/…/public_html/eastwindupchronicle/wp-blog-header.php on line 14

I’ve confirmed that wp() does exist in the wp-included/functions.php file, which gets included from wp-settings.php. The only file I did anything with was wp-config.php.

I did revert to the wp-configsample.php file, but it didn’t have my database connectivity information, so I restored a backup wp-config.php in the end. Still, the wp() function is not being found.

How can I find the wp() function again? Or might the problem be with something else missing in the restored wp-config.php?
