O error that appeared to me at several blogsWordPress After they were moved from one server to another and had edited the file wp-config.php. “Call to undefined function wp() in wp-blog-header.php“.
Cause error: – It seems that the file wp-config.php He loses his lines after he is edited. Specifically, the entire PHP code appears on a single row. I don't know what the exact cause is. Probably a PHP file editor's problem.
