Matthew,
Thanks for your help with this. I do have .htaccess in my directory, public_html/memorial, which is where I installed Backlight. But I think you put your finger on the issue.
I had modified .htaccess by adding the code below, so that I have SSL throughout the site, including in the authentication window where users enter login credentials. (The directory was password-protected, but I have removed the protection while we troubleshoot.)
SSLRequireSSL
ErrorDocument 403 https://memorial.wedelberg.net/
That code got around two issues that I was having with more conventional code used to force SSL – namely, no SSL present when user enter their login credentials, or double-authentication required to gain access to the site. (The alternative code suggested by two Bluehost elevated support staff had resulted in those issues.)
I have more information on symptoms:
(1) With the above code included in .htaccess, images do not display at all in the album, when I go directly to the album’s url at https://memorial.wedelberg.net/we-toplevelgallery/charlotte. There, I find an error message in the padlock saying that some of the content, such as images, is not secure. Moreover, if I go directly to the top level gallery’s url at https://memorial.wedelberg.net/we-toplevelgallery, and click on the album link, I am taken to the home page.
(2) With the above code omitted from .htaccess, images do display correctly in the album, if I go directly to the album’s https:// url above. But if I go to http://memorial.wedelberg.net/we-toplevelgallery/charlotte (plain http:// prefix), I am not redirected to the https:// version, and the album does not display correctly. Same result, if I click on the album’s link on the top level gallery, at https://memorial.wedelberg.net/we-toplevelgallery.
I am way out of my depth here, but I suspect I am doing one of two things wrong: either (a) incorrect code for adding SSL throughout the site; or (b) I have Backlight incorrectly configured for extending SSL to the uploaded images. In any case, if you could point me in the right direction, I’d really appreciate it.
Thanks again for your help.
