# Authentication Required

 * I have this plugin installed on multiple sites, and I have had the same problem
   on 2 sites. I have a completed, published gallery and when anyone goes to click
   on an image which will enlarge it in the lightbox, they get a popup box titled“
   Authentication Required” that asks for a username and password.
 * Keep in mind 2 things:
    1. The gallery functions worked just fine for months 
   before this started happening. 2. I have no other plugins activated on the site.
 * What could be causing this?

 * Thanks for contacting us. Note that we do not have Authentication option in our
   product coding. It might be a permission set up from your server (you need to
   contact your hosting provider) or set up of your theme. Thanks.

 * Thank you for your response. It makes sense to me since I have this plugin active
   and working normally on another site. I have already moved to a different gallery
   plugin, but I do still have this plugin running on another site and would like
   to use it again in the future for other sites. Can you tell me what permission
   level the photo gallery folder and the images inside should be in order to work
   properly without compromising security? Thank you.

 * Thanks for your feedback. The gallery image folder permission should be 755 or
   higher. But this doesn’t require Authentication, unless that’s set by your hosting
   provider.
