We recently migrated from Plesk 10.4.4 Update #59 on Debian 6.0.10 (squeeze) to 12.0.18 Update #62 on Ubuntu 14.04.3 LTS (trusty). This all seemed to work fine until I tried to use phpMyAdmin.
If I use my admin account to login via Plesk try to use webmin (phpmyadmin) I can successfully manipulate all databases (including those users created for their websites). However if I login as a user via Plesk and try the same with their own database I get:
---
Welcome to phpMyAdmin
You probably did not create a configuration file. You might want to use the setup script to create one.

Cannot connect: invalid settings. ---
Clicking the link gives me:
---
Error in Processing Request
Error code: 404
Error text: Not Found

The old environment on the Debian server also used a Apache alias on /phpmyadmin to a non-Plesk maintained version of phpMyadmin in /usr/local/share. Although I figure this might also work I would prefer the Plesk maintained version instead. I also tried to apt-get install phpmyadmin but then it indicates that it will remove plesk packages which are vital. So I opted not to go ahead with this.
