[SOLVED] Error message on site, admin login doesn't work anymore

[ilikedirt]

Hi,

I have a CMS site, that I moved from one domain to another. I changed the root_url in the config.php to the new domain. Now I have this error message on the site:

Warning: Unknown(): open(/var/tmp/sess_5114a74836e2a4afc250a5ce310caaa2, O_RDWR) failed: File too large (27) in Unknown on line 0

Warning: Unknown(): Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/var/tmp) in Unknown on line 0

I'm not even really sure this is directly related to the domain change... Also the admin login seems not to work anymore suddenly - it rejects my passwort.

Please help

Best Regards

Well... the error is gone and the admin login works again... I didn't change anything so this seems to be a hoster issue? But still, how can this happen and what causes it?

Hello,

according to the error messages it is a problem of session management at the PHP level.
Definitely a hosting issue to me, not a CMSms issue.
This is why working PHP sessions are required.
