Cant get plugins to show up on multi sites

I am new to using Multi Site but so far its been great. I noticed an issue today that no plugins are showing up on the multi sites I have created. As a I looked into it I believe I have to change something in the config file to get the plugins to work. I am using Flywheel for hosting and I do not have access to the wp-config file. Any ideas on how I can get the plugins to work on all of my sites? The first one I tried was SmartCrawl.
