First Login not possible: CSRF token is not valid

soph

Hi,

I'm trying to install CollectiveAccess on my host (Ionos).
After the installation, I try to log in and get the following message: CSRF token is not valid

The log shows the following:
2025-10-17 9:39:59 - INFO --> [LOGF] Failed login with redirect for user id '' (/);

The information I found about this in the forum hasn't helped unfortunately.

Any ideas on how to fix this?
Many thanks

For some reason adding this to setup.php fixed it:

define("CA_URL_ROOT", "");

what did you put inside the quotes?

SOLI

i have same problem with version 2.0.9 on Ubuntu 24.04.3 LTS
i also added define("CA_URL_ROOT", ""); in setup.php file but same as ago without edit quotes
below is my server information
i deployed on my localhost with ip 172.16.1.*
CollectiveAccess version: 2.0.9
OS: Ubuntu 24.04.3 LTS
PHP: (8.3.6)
setup.php excerpts:
CA_BASE_DIR: /var/www/collectiveaccess
CA_URL_ROOT: ''
sessions dir owner/perm: (ls -ld /var/lib/php/sessions)
Actions tried: synced NTP, cleared browser cookies, set CA_URL_ROOT, chown/chmod sessions, cleared cache, removed install flags, restarted apache/php-fpm.
Repro steps: 1) Open /install 2) Fill forms 3) Click continue -> CSRF token is not valid. Occurs in incognito and multiple browsers.

somebody tell me must to setup with https and domain to fix this issue!
