The frontend does not match Zabbix database

[HeadQuaker]

Hello,

First the settings :
Ubuntu 18.04
Zabbix 5.0
php : 7.3

Needs : upgrade to zabbix 5.4

The issue :
I am following the upgrade procedure but everytime in the end, i got that issue :

The frontend does not match Zabbix database. Current database version (mandatory/optional): 5040000/5040000.
Required mandatory version: 5000000. Contact your system administrator

The DB is updated, no issue in zabbix logs, when i check the version of the frontend, it is in 5.4 version but still got that error.

Any Help ?

Regards

If the frontend package has been upgraded to 5.4, try restarting your web server or php-fpm.

Hello,
it is the first thing i did, even restarted the server.

it seems that after upgrading everything, the file /var/www/zabbix/include/defines.inc.php still saying that zabbix is in 5.0

I am fedup with all this, each upgrade is a fight against something different

Any idea

OK found the issue, last time when i upgraded to 5.0 i used the sources, and now i used the package. It seems that folders are different.
