   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 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.
   Thanks
