[SOLVED] Exception in session_start();

Hello there,

i've got this msg on a clean intallation of grav on a shared host. I've examined the the php_info and i found, that the APC support lacks.

I guess there is no workaround, isnt there?

Thx in advance.

Whoops\Exception\ErrorException thrown with message "session_start(): open(/tmp/sess_25d414f6918d0b86728b06863d588172, O_RDWR) failed: No such file or directory (2)"

I had a similar issue (I think) on CentOS7. The PHP session.save_path did not exist and thus was not writable by the webserver user (/var/lib/php/session in my case). You can find the PHP session.save_path in your php_info. I am not sure if this is the same issue.

Thk u. I am gonna check on this. Thats weired. I run grav on two different web hosters without any install issues. Only this time.... I will keep u up to date.

I just figuered it out. I wrote a test application. Simply, its an issue related to read/write permissions. The session_start() function stores all session keys in the session.save_path in order to trace the state of the http connection. So i only had adjust the user permissions, but... ... ... ... ... ... ... ... ... ...
it a polish hoster and the whole backend sounds to me like an alien language ;(
