Plugins Not Showing in Wordpress Dashboard

In my wordpress dashboard under wmpu dev plugins show 1 update needed but when I go to the plugins portions of wpmu in wordpress it says No Plugins found. I know wp-smush is / was set up in there and used, but I can't seem to get to it any longer. There is no way to add plugins either. And even the dashboard itself is strange. The profile pic is huge in the center of the page and instead of the page being styled as it normally is everything is straight down the left side of the page. This is the second site like this. I've tried uninstalling and reinstalling wpmu. Any ideas?
