IE error in Oxfam image drawer when previewing newly-uploaded image

[Stefan Walluhn]

When adding a new image to a page with the help of the mceEditor (insert/edit Image -> Upload New), it fails with several error messages like:
* j is undefined
* Cannot read property 'upload_image_info' of undefined

Nevertheless the image is uploaded and available under "My Recent"

Did some investigation on this. I can recreate this on oxfamstaging under IE10. However, I can't recreate it on OSF production or staging, nor on a local sandbox.

I looked at the IE10 console and the network traffic. The image is indeed uploaded fine. It appears to be an error caused when we show a local preview of the image. The IE10 console has a number of errors such as:

SEC7111: HTTPS security is compromised by res://ieframe.dll/bullet.png

After doing some research, I believe this is related to the custom security used for Oxfam's SSO implementation triggering the warning. Back to gocept to decide on the next steps.

Closing due to lack of interest.

We were able to identify the issue: It is caused by a framing prevention header we added in the frontend nginx config for security reasons. After disabling the header image upload works as expected.
