I have encountered a strange issue.
On this site we formerly had the Admin Tools password protection applied on the /administrator folder for a long period. About 2 months ago we had to remove the protection. This was done by removing the .htaccess and .htpassword files from the directory. Since this change we do not see the htaccess login prompt anymore - as expected.
But now we have a strange issue with a (temporary) super user (located outside Europe) who can't reach the Joomla login page because he is first prompted with an htaccess login box.
I can assure you that there is no .htaccess or .htpassword file present in the /administrator folder.
My guess is this is not Admin Tools related, but since we have used your feature on this site it's the only clue I have at this point. I have searched the documentation and the tickets for a similar situation but couldn't find one.
What could cause this issue?
Thanks in advance,
