I’ve narrowed this down to bbpress and have read up a load of suggestions but none seem to work and I can’t get rid of this error message which leaves the rest of the admin page blank.

The message I get is:

Notice: bbp_setup_current_user was called incorrectly. The current user is being initialized without using $wp->init(). Please see Debugging in WordPress for more information. (This message was added in version 2.3.) in /home/xxxx/public_html/home/wp-includes/functions.php on line 3901

Followed by

Warning: Cannot modify header information – headers already sent by (output started at /home/xxxx/public_html/home/wp-includes/functions.php:3901) in /home/xxxx/public_html/home/wp-includes/pluggable.php on line 1171

The first message I understand is a noted bug which I can ignore.

The second appears only when bbpress is activated (even with no other plugins activated on a new 4.5 installation of WP is there).

I’ve checked /wp-includes/functions.php and there are no spaces at the beginning or end of it (as suggested on another thread as a possible cause) and likewise /wp-includes/pluggable.php has no spaces.

What else might be causing this error and can I do anything about it?

Many thanks for any help here…

/home/xxxx/public_html/home/wp-includes/functions.php

		}
	}

Is the function, line 3901 is : trigger_error( sprintf( __( ‘%1$s was called incorrectly. %2$s %3$s’ ), $function, $message, $version ) );

I have the same problem. I have a blog and most of my audience are beginners who want to create a blog and make some income out of it. I wanted to have a discussion forum where my audience could post their queries.That’s why I started using bbPress but I keep getting this error “cannot modify header information”.

Any help would be appreciated.
Thanks
