I have the next problem in the sites with the Akeeba Profesional for WordPress:
Warning: session_start(): open(/tmp/sess_75f2v2apl6mpcdei2pgkab8fb4, O_RDWR) failed: Permission denied (13) in pen(/tmp/sess_75f2v2apl6mpcdei2pgkab8fb4, O_RDWR) failed: Permission denied (13) in /home/jdev2016/public_html/wp-content/plugins/akeebabackupwp/helpers/AkeebaBackupWP.php on line 51
Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /home/XXXXXX/public_html/wp-content/plugins/akeebabackupwp/helpers/AkeebaBackupWP.php:51) in /home/XXXXXX/public_html/wp-content/plugins/akeebabackupwp/helpers/AkeebaBackupWP.php on line 51
I think the problem is related with the cookies and the "~" in the path of my website. I use Siteground and Cpanel and the path in the sandbox o develop site is for example: http://107.6.160.98/~XXXXXX/wp-admin
If I erase the cookies the problem dissapears.
Any suggestion?
Thanks a lot!
