Hi!
Warnings are appearing in the server’s error log:
PHP Warning: Cannot modify header information - headers already sent by (output started at /wp-admin/includes/template.php:2670) in /wp-content/plugins/akeebabackupwp/app/Solo/Controller/Backup.php on line 119
The Wordpress and all plugins are up-to-date

The problem actually does not come from our plugin, but from a different plugin which has already sent HTTP headers (or produced output, even if it's a single space or newline character) before our plugin loaded. When our plugin tries to start a PHP session, PHP realizes it has already sent output to the browser and complains.
