Error when editing PHP Configs = basic or advanced

I try to edit php config to increase upload_max_filesize according to tutorial here 4 - Change Upload Limit for phpMyAdmin - 08 - Server - CyberPanel Community

but always errors cannot be edited. I use php 7.2

Which CyberPanel version you are using?

Cyberpanel 1.7
Build 1

what next ?

Please upgrade 02 - Upgrading CyberPanel - 01 - Install/Upgrade - CyberPanel Community

399/5000
I have upgraded. succeed thank you

but there is a new problem.

when opening phpmyadmin an error like this appears

phpMyAdmin - Error
Error during session start; please check your PHP and/or webserver log file and configure your PHP installation properly. Also ensure that cookies are enabled in your browser.

session_start(): open(SESSION_FILE, O_RDWR) failed: Permission denied (13)

this error when I open it in browser chrome (which I always use)

when I try it in another browser (for example Firefox) successfully open phpmyadmin without error

Try incognito on chrome.

successful when trying incognito

why is that?

maybe clear your browsing history. I think your old session key is no more.

oke thank you
