Here is my problem. When I make a backup the following message appears :
Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /*****/*****/www/wp-includes/functions.php:2504) in /*****/*****/www/wp-content/plugins/woocommerce/woocommerce.php on line 138
But the backup seems to end successfully : a new extentionless file is created on my drive account.
Is that normal? Do I have to worry about this issue?
Thanks for support.
