[Plugin: NextGEN Gallery] Flash uploader does not work with https

I’ve just started using NextGEN Gallery 1.6.2 and encountered a problem very similar to that described in this thread. The difference is my site url includes https instead of http.

• Tried to upload multiple files with ngg flash uploader. Received “ERROR HTTP ERROR : PICTURE_NAME.JPG : 302″ with every file.
• Doubled relevant php.ini settngs(see below for list) and retested with no change in results.
• Tried to upload a single file with the flash uploader disabled. This worked.
• Changed WordPress Address and Site Address on the WP Options page to use http instead of https.
• Tried the flash uploader with just two files. The upload was successful.
• Changed WP addresses back to https
• Tried the flash uploader with just two files and again recieved “ERROR HTTP ERROR : PICTURE_NAME.JPG : 302″
• Tried the WP core flash uploader, creating a new post and uploading two files. The files uploaded successfully and are displayed in the post.
• Tried to upload a single file with the ngg flash uploader with https set. Progress bar increased to 100% and the the following message was displayed in a yellow box at the top of the page: “0 picture(s) successfully added”. I checked the gallery and the picture was not added.

Based on the link referenced above and the above testing, it appears that the https in the WP addresses is the limitation. I’ll be able to work around it, but the multiple file upload is a very useful feature. I’m hoping it’s a simple fix.

I also tried to upload a zip file, and this appears to be a completely different issue (and probably belongs in a different post), and received “Uploaded file was no or a faulty zip file ! The server recognize : application/empty”. I tried changing max_execution_time, max_input_time, memory_limit, upload_max_filesize, post_max_size, default_socket_timeout and they had no effect. Regardless of the settings the above error message displays in about 75 seconds. The zip file is less than 1/2 the size allowed by php. I also tried the zip upload using both http and https and saw the same results with each.

I’ll work around these issues by changing to “Maintenance Mode”, changing to http, uploading multiple files with the flash uploader and then changing back to https.

Thanks,

Shawn
