failed to open stream: No such file or directory

I keep getting this error message when I try to log in to wordpress at
https://anniehearts.com/wordpress/wp-admin

Warning: require(wp-blog-header.php) [function.require]: failed to open stream: No such file or directory in /home/anniehea/public_html/index.php on line 17

Warning: require(wp-blog-header.php) [function.require]: failed to open stream: No such file or directory in /home/anniehea/public_html/index.php on line 17

Fatal error: require() [function.require]: Failed opening required ‘wp-blog-header.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/anniehea/public_html/index.php on line 17

Earlier today, I moved what used to be my wordpress blog (in an iframe on iweb) to the wordpress root directory. I’ve deleted my iweb files and now only have the wordpress site.
My used to be at annihearts.com/blog
and now it’s at
anniehearts.com

Every time I try to log in, I get the error message above.

Any help is appreciated.
