WordPress 3.4.2 Fatal Error - on Mobile Phones only (1 post)

    On any mobile phone when I try to view my site I get the following error:

    fatal error, unknown cannot use output buffering in output buffering display handle is unknown on line 0.

    No website page is displayed at all.

    I use WP Supercache - I have taken out the mobile device lines in the htaccess file and disabled the mobile option in the setting screen as I am not using a mobile phone viewer plugin.

    Can anyone help why this is happening. Any help is highly appreciated.

    Here is my HTACCESS file:

    # WordPress htaccess
    
    ExpiresActive On
    ExpiresDefault "access plus 300 seconds"
    
    ExpiresByType text/html "access plus 1 day"
    ExpiresByType text/css "access plus 1 day"
    ExpiresByType text/javascript "access plus 1 day"
    ExpiresByType image/gif "access plus 1 month"
    ExpiresByType image/jpg "access plus 1 month"
    ExpiresByType image/png "access plus 1 month"
    ExpiresByType application/x-shockwave-flash "access plus 1 day"

    This site works fine on pc browsers. Any help will be highly appreciated.
