The site is environment.wiki and hosted by greengeeks - I welcome all help on this project as I am not a developer :)
I need to find the localsettings.php file so I can a. change the logo b. get external links to open in a new tab c. Figure out how to add a large library to the directory called phpspreadsheet d. Update the media wiki version ( so far not able and unsure why)
All advice about running a media wiki site is welcome! I picked media wiki because it seemed easy for others to help.
I looked everywhere in the file list for commonsettings or anything similar. Softalicious managed the install
