hi all havent been on here for a while and ive forgot more than i remember so im in need of help. I have followed, The Perfect Server - Ubuntu 16.04 (Xenial Xerus) with Apache, PHP, MySQL, PureFTPD, BIND, Postfix, Dovecot and ISPConfig 3.1 i have been having problems as originally the email button that links to the email didnt work from the ispconfig dashboard and neither did /webmail returning a 404 error as it really didnt exist. I finally spooted in the settings for email in ispconfig 3.1 has the alias of /webmail but the tutorial sets the alias up on page 3 as /roundcube which i have found out this morning but before i did i had completely mucked up the email side of it trying to get squirrelmail to work as i didnt know roundcube was an email client. S i did apt-get remove for squirrelmail and roundcube I have gone through the set up again and the button works and it opens roundcube Hoorah but the this error pops up DATABASE ERROR: CONNECTION FAILED! Unable to connect to the database! Please contact your server-administrator. i have to roundcube databases now in phpmyadmin roundcube and roundcubedb so i need helpchecking the settings and curing the mysql error for the roundcube db i have mucked up. please i am a dummy so please explain each step.
