on Chrome the admin password popup shows up

hello
on google Chrome and IE a popup shows asking for authentication required.

when u open a post on google Chrome and IE, it shows a server login screen asking for a password and username,

that pop up is the one i use on cpanel to protect my wordpress admin login, but for some reason, it shows using this plugin

i tried diferent themes: same issue. its the plugins fault.
tried disabling the plugin: site opens OK . issue fixed.
tried not disabling socialite: not sure if this is the issue, im having headaches, need to look for a new plugin.

its not my site or server, since i tested it on diferrent sites and servers and is the same issue with just this option.
