I've just uploaded a fresh wordpress installation to http://www.therealcaffeine.com/. When I load that page it gives me the following error:
Fatal error: Call to undefined function: wp() in /home/content/t/h/e/thercaffeine/html/wp-blog-header.php on line 14
I know my host's database is working, and that it can run wordpress because it has before. The same installation (albeit with different database information) worked on my local server. I've checked the forums, and I do have a wp-includes directory, where all files are present (specifically functions.php) and none are size zero. All three directories (wp-content, wp-admin, and wp-includes) have permissions 755. Is that the correct permission? And what else can I check to get my blog running?
