New installation - Error 400 bad request on every edit and save

[marcin.fig]

Hello,

I've just installed fresh new version 6.1.3 of EspoCRM, everything went smooth, I have all system requirements checked successfully, I even set 'aclStrictMode' => false in condig file but I have one issue.

Despite I'm able to add new client or new user, a problem occurs when I try to edit something and save it. On every form I get error message popup "Error 400 Bad Request". It is when I want to edit some field of previously added client or edit any other form throughout the system.

Can anyone help me how to solve it.

Best regards,
Marcin

Hi,
I tried to reproduce but didn't face such issue.
What are your web server and CLI PHP version? You can check the web server PHP version in Administration -> System Requirements. PHP CLI version you can get by executing this command in terminal: php -v
