Wp-admin blank page [solved]

  • I tried to log in a client website, but the result was a completely blank page on wp-admin/
    After a lot of search in the wordpress files I decided to look the admin error_log (which I should have done first) and I found this:

    [23-Apr-2013 12:53:46 UTC] PHP Warning: Cannot modify header information – headers already sent by (output started at /home/muuvai/public_html/ftps/valdez/wp-content/plugins/posts-for-page/posts-for-page.php:23) in /home/muuvai/public_html/ftps/valdez/wp-includes/pluggable.php on line 876

    Found two things that I fixed and it came back to life.
    First, a tabbed space in the line 876 in pluggable.php and a whitespace at the end of the first <?php> function in posts-for-page.php (line 23).

    I’m not a developer so I have not exact idea of why this happened, but I kinda fixed it so I’m sharing the info for other people.
