phpmyadmin not working, roundcube (CentOS)?

Question

PHP

Hi all!

I installed ISPmanager 5 Lite, but phpmyadmin and roundcube did not take off.

Before that, I installed Bitrix Environment, screwed up the site. But then I decided to install ISPmanager (with the recommended software)
and eventually got an error:

Mysql connect error [localhost, 127.0.0.1]: Access denied for user 'root'@'localhost'

- started mysql in skip-grant-tables mode

Then removed the HTTPD=/usr/sbin/httpd.itk line in the etc/sysconfig/httpd file and set HTTPD=/usr/sbin/httpd
because apache didn't start.

Tell me how to connect properly phpmyadmin and roundcube
Thank you in advance
