(also tried on 1.9.2/1.5.5 installation with same results)
Some server info (it's shared hosting server):
* Operating System : Linux (32 Bit)
* Server : Apache/2.2.16 (Unix) mod_ssl/2.2.16 OpenSSL/0.9.7a mod_fcgid/2.3.5 Phusion_Passenger/2.2.15 mod_auth_passthrough/2.1 mod_bwlimited/1.4
* PHP Version : 5.2.14
* PHP Safe Mode : Off
* PHP Allow URL fopen : On
If I enable ssl for admin area with FORCE_SSL_ADMIN flag in wp-config, then flash upload of images is not working. Non-flash upload is still working.
When doing the upload with flash, then I can normally choose the images that I want to upload, I choose the album, and when I click on Upload button then I briefly see some login fields (username, password) inside the right frame (in "Upload images" tab), maybe for 2 or 3 seconds, then those fields disappear and upload form is displayed again, it's reset, and a message is displayed above in yellow bar "0 picture(s) successfully added".
Is there some problem with ngg/flash and ssl or is there just some problem with my setup?
