This was resolved earlier today in Discord so I will mark the thread as [Solved], but please raise a new request if you get stuck. Please note that it is sufficient to raise a request in one place only to avoid duplication of effort, since all support is done by volunteers who help out in our free time.

For reference for anyone else searching the forums with this issue: Linux is case sensitive, so Mysql.php and mysql.php are different files, and we can see in the error message that the system could not find the file named Mysql.php with a capital M. 
We have a troubleshooting page in our Wiki that covers Linux case sensitivity issues, for more details: https://wiki.helionet.org/common-errors/linux-case-sensitivity
