I found a problem related to your files
engine_functions.php
and system_m.php
Did you add two files before? you can file these files via template folder => features folder
Your issue related to php version https://stackoverflow.com/questions/46630924/call-to-undefined-function-set-magic-quotes-runtime
If you add these files before, please check and make sure the coding syntax compatible with php 7 version
Its a problem with hosting permission that the component can not replace/move file while installing.

Can I take a look your hosting info to check?
“Futhermore, I can not see the pages made with Quix”
Quix uninstalled before that why you cant see the page built with quix, the solution is reinstall quix but we’re facing the issue with permission.
For this case, could you please enable ftp account via joomla configuration then try to reinstall the quix again ?

Add the ftp account then install the component with your ftp account permission.

Hi Timothy,
Are you able to install the Joomla quickstart package before? It seems an issue with hosting.
Please check and chmod all Folder => 755 and files => 644 then recheck.
Most hosting provider did it automatically, some require manually when unzip the package.
Let me know the result.
