Fixing the "Invalid or Missing Session Save Path" Error

If you see an error like:

Invalid or missing session save path: /var/lib/bolt-php/session

this usually means your server is not currently configured to allow PHP sessions to be created using the session path reported by PHP.

Summary

This is typically a server or hosting configuration issue, not a problem caused by Event Espresso itself.

Event Espresso relies on PHP sessions, but it does not define the server's session save path. It only uses the PHP session settings already configured on your server.

Why This Happens

PHP needs a valid, writable location on the server to store session data. This error can appear when:

The session directory does not exist
The session directory is not writable by PHP
The server has an incorrect session.save_path setting
Server restrictions are preventing PHP from creating session files

What Event Espresso Does

Event Espresso does not set the session save path shown in this message.

Instead, Event Espresso reads the PHP session configuration provided by your server and attempts to use it. If that location is invalid or inaccessible, this notice is shown.

How to Fix It

In most cases, you will need to contact your hosting provider or server administrator and ask them to check the PHP session configuration for your site.

Send them the full error message and ask them to verify that:

The PHP session save path exists
The PHP session save path is writable by the PHP process
The session.save_path value is correct
No server restrictions are blocking session creation

Message to Send to Your Host

You can copy and paste this message:

I’m seeing this error in Event Espresso:

Invalid or missing session save path: /var/lib/bolt-php/session

Please check the PHP session configuration for this site. It appears PHP cannot create sessions using the current session.save_path .

Can you confirm that the directory exists, is writable by PHP, and is correctly configured for this account?

If your site shows a different path, replace the example path with the one from your error message.

Frequently Asked Questions

Is this caused by Event Espresso?

Usually no. This message points to a PHP session configuration issue on the server.

Does Event Espresso require sessions?

Yes. Event Espresso requires PHP sessions to function properly.

Can I fix this inside the plugin?

Usually no. Because the session path is provided by your server’s PHP configuration, this normally needs to be corrected by your host or server administrator.

What should I do after my host makes changes?

After your host updates the server configuration:

Refresh your site
Test registration or checkout again
Confirm the message no longer appears

What if my host says everything is correct?

If the error continues after your host reviews the server settings, contact Event Espresso support and include:
