I have a strange issue. I have two types of banners on my side. Banners to advertise my own content, so they are linked to the same domain. And Banners to external content, so they are linked to an external domain.
One thing that seem to be involved here: I secured my WordPress backend (the folder "wp-admin") with htaccess...
And the problem is this, when I klick on a banner that is linked to an external domain, I'm prompted with my htaccess-login. When I click on one of the banners to my own side, everything is fine.
So is there some kind of query back to the WP admin-area, when I click on external linked banners? And how can this be turned off?
