No login after Update from 17.0.2 to 18.0.2

I mad a update from 17.02 to 18.0.2. The installation run whit the Web interface. A Da later i try to login but i get the information " wrong password" .
I found this article:

Got a similar problem with my cloud a few days ago. When updating from 15.0.7 to 16.0.1, it stopped login me on web side. My solution was changing, on the php config (etc/php7/apache/php.ini), the configuration for the maximum POST size

max_post_size = 10G


max_post_size = 10737418240

And then restart the apache web server

I try the same an add in my php.ini
max_post_size = 10737418240

My knowledge in this area is not that good. Maybe someone can help me with the entries.

There are two text boxes, one is for administrator and one I can add parameters.

in the first text box administrator Are the following entries

mysqli.default_socket = /var/run/mysqld/mysqld.sock
mysql.default_socket = /var/run/mysqld/mysqld.sock
pdo_mysql.default_socket = /var/run/mysqld/mysqld.sock
pdo_mysqli.default_socket = /var/run/mysqld/mysqld.sock
mysql.allow_persistent = Off
mysqli.allow_persistent = Off
curl.cainfo = /etc/ssl/certs/ca-certificates.crt
upload_max_filesize = 50M
post_max_size = 50M
display_errors = Off
memory_limit = 256M
session.save_path = /tmp
error_reporting = E_ALL & ~E_NOTICE
date.timezone = ‘Europe/Berlin’
expose_php = Off


In the Textbox My Entries
upload_max_filesize = 150M
max_execution_time = 180
max_input_vars = 5000
post_max_size = 150M
memory_limit = 1024M
max_post_size = 10737418240

I am not sure if this ok like that, ore I have to change something.

Did you check the logfiles? Could also be that the db server is down or something like that.

like @tflidd said… you definitly should check the logs… and maybe it’s gonna tell you about some missing db-tables after update… (you could find that as well under set-up of your admin account)
