Fatal error: Unknown: Cannot use output buffering in output buffering display..

  • I get this “Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0” on my custom post type archive page when I activate All In One SEO plugin.

    And below error I get when I remove ob_start() from the header

    Fatal error: ob_end_flush(): Cannot use output buffering in output buffering display handlers in /home/savadam/public_html/wp-includes/functions.php on line 3269

    It would be great if someone could help me with this.

    Thanks.

  • Hi jery61007,

    First, try deleting and reinstalling the plugin from the WordPress plugin repository; second, there is an option under All in One SEO -> Performance for Force Rewrites, set this to Disabled and click Update Options.

    Hi Peter,

    Thank you for the reply. Actually I had downgraded it to previous version and it worked. However, I updated the plugin as you said and the problem has been fixed.

    Wish you a Happy New Year ??

    Thanks.
