every single of hotel booking installation produces this error:
PHP Warning: Cannot modify header information – headers already sent in /web/nadmorski/wp-content/plugins/motopress-hotel-booking/includes/libraries/wp-session-manager/class-wp-session.php on line 137
within my debug log.
Could you please let me know if i should be concerned about it??
And if its in any way related to my sync logs not being ever deleted??
I appreciate your help .
