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 
?
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
