    Hi guys, Im getting this error when I try to activate the 'sharing' module of jetpack...

    Warning: Cannot modify header information - headers already sent by (output started at mydomain.com/wp-content/themes/catch-kathmandu-child/functions.php:26) in mydomain/wp-includes/pluggable.php on line 1121

    I am not too familiar with this, could anyone help me fix the problem?

    I used to use simple share plug-in before... it worked seemlessly, but now I got jetpack and I figured I would just use the module in jetpack... so I deactivated and deleted the simple share plug-in but I get this error instead =/

    Hi,

    It sounds like there is something at in your child theme's functions.php at line 26 that is causing trouble in same way. What's there in your functions.php?
