Warning: session_start() failed: No such file or directory

I'm trying to install berta (v 0.6.3b) and I get this error:

Warning: session_start() [function.session-start]: open(/var/php_sessions/sess_a0d6b8422181739d10066fb60cebfe5d, O_RDWR) 开发者_Python百科 failed: No such file or directory (2) in /hermes/bosweb/web010/b100/ipg.ellieniemeyercom/engine/_classes/class.bertasecurity.php

on line 75 The error seems to happen on line 75 of class.bertasecurity.php (view source code)

What is wrong and how can I fix it?

Make sure that session directory is writable or you can set a path yourself with:

session_save_path

This comment is also useful if you are using above function.

---

I think the folder containing the session data cannot be accessed by the PHP process.

If you have not touched your php.ini, the default session.save_handler should be files (which means that session data will be stored in a folder on your file system). The value of session.save_path contains that folder, you should check that it exists and its permissions for your php process.

---

If you're changing the path that is being used for sessions.

You also might consider, fixing this problem by changing session.save_path variable in your php.ini file.

Then you'll be fixing in your configuration file and not only in your script.

---

Sessions are saved on the harddisk of your server. Most likely your session save path does not exist. Try setting it to a directory that does exist or that you have read/write rights to.

We encountered this problem when migrating a website from a cPanel server to a different host.

The session.save_path was configured in php.ini and .user.ini inside our public_html/ folder, and was presumably overwriting a default path the host would have wanted to use.

We decided the files were not needed at all, just a hangover from the old server, and deleted/renamed them out of the way, and this fixed the problem.
