Error in my wordpress

Try reviewing Solving “headers already sent” warnings.

still not working.

And what exactly did you do?

I added this to my functions.php file

add_filter('init', create_function('$a', 'global $wp_rewrite; $wp_rewrite->author_base = "user"; $wp_rewrite->flush_rules();'));


And when I enter in a post_type, shows me a 404 but if you let me edit.

I meant after the error appeared. Did you read the page at the link posted above? Did you check your wp-config.php file?

yes, this correctly.

So you edited your wp-config.php file?

I tested my theme in another WordPress installation and no errors. The only thing is that the post_type shows “Error 404” when I see them.

The wp-config.php file is correct. I downloaded again even.
