Attach Gallery pop-up opens blank

@corvidism – We have had reports of issues with mixed HTTP/HTTPS installations (although we have not been able to recreate them ourselves) … we are also looking at modifications to correct for these reports.

We do hope to have this sorted out with the next major releases (2.0.67+) … until then, if possible please go to site wide HTTPS protocols (or HTTP protocols) and at least clear the image cache afterward under Gallery > Other Options > Miscellaneous.

In some cases you may also need to use the Reset Option under Gallery > Other Options.

– Cais.

Hello again,

I have discovered what exactly was causing the problem:

We are using WordPress HTTPS to secure only wp-admin, and everything else to use plain http. (“Force SSL Administration” and “Force SSL Exclusively”) This results in every non-admin site to redirect to http.
This then causes the blank ‘Attach NextGen Gallery to Post’ window, because the url you are using to load the data (“[siteurl]/nextgen-attach_to_post”) isn’t recognized as a part of admin (there is no way the HTTPS plugin could know it’s a part of backend, the url looks like a page). So it redirects it to http, and gets blocked by the browser.

I fixed it by setting the url “/nextgen-attach_to_post” to be specifically secured by https, and it works now.

That said, would it be possible for you to use a different url? We can’t be the only ones with this issue, and the solution is far from intuitive.
ALso, the native ajax functions wordpress supplies don’t cause something like this.

Anyway, thank you for your time.

This shouldn’t be a problem with NextGen 2.1 anymore as we load the ATP iframe via admin_url() which should play nicely with WordPress-HTTPS. If this is still an issue please let me know-I could add a filter to WordPress-HTTPS’ ‘force_ssl’ to make our ATP preview always be HTTPS.
