If we get an error given below while accessing phpMyAdmin.
Cannot start session without errors, please check errors given in your PHP and/or webserver log file and configure your PHP installation properly.
Inference
By looking into the error, we expect that there can be error in writing session files. Either the owner do not have ‘write’ permission or the owner is different.
Solution
Normally tmp directories are used to dump sessions. And phpMyAdmin has its own tmp folder. Check the permission and ownership of this folder. Change it to the following
Location : /var/cpanel/userhomes/cpanel-phpmyadmin
$ cd /var/cpanel/userhomes/cpanel-phpmyadmin
1) Permission of tmp must be 700
$ chmod 700 -R tmp
2) Ownership must be cpanel-phpmyadmin
$ chown cpanel-phpmyadmin: -R *
The output should look similar to as given below
$ ll /var/cpanel/userhomes/cpanel-phpmyadmin/
