I wanted to remove a user from the main site, but this is the alert:
“Warning: Cannot modify header information – headers already sent by (output started at /home/xxx/domains/xxx/public_html/wp-content/plugins/multisite-toolbar-additions/multisite-toolbar-additions.php:878) in /home/xxx/domains/xxx/public_html/wp-includes/pluggable.php on line 875”
I reloaded the page, still the same error and nothing else (except the Notice I posted on a previous thread), but going back with the browser showed the user was actually deleted from the specified webiste.
So, what is that warning about?
