Images missing in https

edited November 2018 in Troubleshooting

I'm setting up a new installation of Collective Access and everything was working well until we turned on security forcing https. Now the images do not render correctly. When I look at the media basic information for an object and copy the image location, I get

The image is available and viewable at

Consequently, something in CA is forcing http instead of https. I have also noticed that is being rewritten as, that is providence is missing in the path.

Any suggestions where I might look to change this, please.

  • In v 1.7.6, you can define CA_SITE_PROTOCOL in your setup.php file (around ln. 244) as "https" and that should force images to be linked properly.

  • Thanks, I forced CA_SITE_PROTOCOL to be 'https' which has fixed Providence. Unfortunately, adding define("CA_SITE_PROTOCOL", 'https'); to Pawtucket didn't help any. Still investigating...

  • Progress - It seems there is something corrupt in my site's .htaccess file, which has a lot of entries. I stripped it back to basics and now Pawtucket is working fine.

  • In the "release" version of Pawtucket 1.7.6, the protocol is hardcoded in ln. 86 of /apps/conf/global.conf, rather than using the defined value from setup.php like Providence does. This issue looks to have been fixed in the develop branch, with both global.conf files mirroring one another.

    Also, it looks like this forum's text editor is stripping out the double underscores wrapping the value name, for any future readers that stumble on this thread.

    The value in question is __CA_SITE_PROTOCOL__
