do you have a sample link or screenshots for us to see? also, have you tried to temporarily:
– deactivating all other plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).
– switching to the default theme to rule out any theme-specific problems

Its a fairly new install and Events manager is the only plugin thats installed under the main admin. There are 4 sites installed under the multisite and it only effects the first site.

something is outputting whitespace somewhere in your install before headers can be output.
have you tried angelonwl’s suggesions? it could even be your theme
