Magento 2 Admin Page Error: Your current session has been expired

Question

Fresh Install of Magento 2.2.2 on Centos (Plesk) with Apache 2.4, php 7.0.2 + all modules, mariaDb 10.1.

Magento Installation was done via browser wizard -> readyness check-> everything was ok. When I try to login to the Magento Admin Page "Your current session has been expired." is always showing.

I am running Magento 2.1.7 on this Server and had the same problem. But I solved this problem by changing one line of Timezone.php (shown in here https://github.com/magento/magento2/issues/5383). However with Magento 2.2.2 this solution does not work anymore.

Any Ideas how to solve this ?

Ps: Already cleared cache folders and cache via cli.

When I run "php -v" via SSH --> php 7.0.27 is shown

I configured Php 7 (via Plesk) for scripts on my domain "/opt/plesk/php/7.0/bin/php -v" --> shows php 7

BUT phpMyAdmin (login to mariaDB) shows this (php 5.6.30):

Maybe this is causing the error ?

Answer 1

• Find path admin/security/session_lifetime in core_config_data table
• If it's present then set its value to 86400
• If that path is not present then add it with value 86400

    INSERT INTO `core_config_data` (`scope`, `scope_id`, `path`, `value`)
    VALUES ('default', 0, 'admin/security/session_lifetime', '86400');

After that, refresh Magento cache:

php bin/magento cache:clean

Answer 2

Try clearing your cache and login to admin.

rm -rf var/cache/*

rm -rf var/page_cache/*

php bin/magento cache:flush

Answer 3

I had enabled Magento Profiler before by adding 'SetEnv MAGE_PROFILER "html"' to my .htaccess. After removing this line again, the error stopped and I can access the admin page.

Answer 4

The solution for Magento ≥ 2.3.7:

bin/magento config:set system/security/max_session_size_admin 0
bin/magento cache:clean

mage2.pro/t/6362

Another message for the same error is «Session size of <…> exceeded allowed session max size of <…>»
