Same bug for me (wordpress version: 4.6.1)

List of installed plugins:
– Contact Form 7
– WooCommerce
– WordPress Importer

Hi,

For the ‘Cannot modify header information – headers already sent …’ error you need to edit the file bp-fp-loader.php and replace the line:

add_action('bp_enqueue_scripts' , 'bp_fp_launch'); – line 147

with

add_action('template_redirect' , 'bp_fp_launch');

I’ve had the same issue.
A quick solution is to edit the file /wp-content/plugins/social-sharing-toolkit/social_sharing_toolkit.php.

Check the lines in the file where the error is reported; there’s an IF statement like:

if ( $this->options[......][$button]['enable'] == 1)

Change the statement with this one:

if (array_key_exists('enable', $this->options[......][$button]) && $this->options[......][$button]['enable'] == 1)

Be aware that the changes you have made will be overwritten on plugin update.
