I checked my PHP logs, and it says that
[16-May-2016 16:42:07 UTC] PHP Parse error: syntax error, unexpected '[' in C:\mysite.com\www\wp-content\plugins\woocommerce-bolder-product-alerts\inc\class-account.php on line 48
Here is that line:
if( $settings_low[ 'enabled' ] == 'yes' || $settings_sales[ 'enabled' ] == 'yes' || $this->get_subscription_settings( $user_id )[ 'restocking' ] ) :
I'm no PHP coder, so does this line look correct?
Thanks.
SOLUTION
$subscription_settings = $this->get_subscription_settings( $user_id );
if( $settings_low[ 'enabled' ] == 'yes' || $settings_sales[ 'enabled' ] == 'yes' || $subscription_settings[ 'restocking' ] ) :
