ERROR with protected page and Won't logged me

This morning , my entire website prompt me with a a Log In and I was not able to log in under any credential.
I tried the Admin user and pw plus a few other user options I previously created and it kept refusing the entrance.

The Log in Box said:
To view this page, you must log in to area Limited on http://www.aafd.org:80

After I cancelled this is the message I received.

This server could not verify that you are authorized to access the document requested. Either you supplied the wrong credentials (e.g., bad password), or your browser doesn’t understand how to supply the credentials required.

Everything worked fine until this morning, and no changes where made in the past few days. So this is very strange.

Only a few pages were protected, NOT the entire site.

Since I had NO way to log back in ( even /wp-adimin was not accessible) I had to delete the 2sMember plug in via FTP and get rid of it.

I don’t know what the problem is and I am afraid to reinstall the plug in, since the website is live and functional I don’t want this to be happening again.

Thank you for your support

Thank you for reporting this important issue.

This is still happening when I try to access http://www.aafd.org/wp-login.php. This protection is NOT something that s2Member is doing. I would strongly suggest contacting your serving hosting company to find out what’s causing this.

Yes, it turned out that the Hosting company detected suspicious malware and added a second lawyer of login. Thank You
