404 Errors on Subsites after Updates


I have a client who site is hosted on GoDaddy.
website: primecatering.ca

I was doing a plugin update and I received a 503 service temporarily unavailable error. The site came back up after a couple of minutes. The plugins are up to date. The main site is up and I can access the dashboard. I can access the Network dashboard.

I can't access the subsites. I have two of them and neither can be accessed. I get the 404 Not found error.


Any help would be greatly appreciated.
