When I want to add an image to a page or static block I use the media gallery and upload a new image.

Unfortunately, when I press the browse button I can select a file. But as soon as I select it, it freezes in all browsers.

I know the media uploader has been updated not to use flash anymore, which is a great improvement. But It suddenly stopped working, and I am not sure how to debug this kind of problem using the inspector.

  • When you say "I know the media uploader has been updated not to use flash anymore" that means you have applied SUPEE-8788 right ? – Raphael at Digital Pianism Dec 12 '16 at 16:39
  • Yes, that is correct @RaphaelatDigitalPianism – xvilo Dec 12 '16 at 18:59
  • I have a small update; it appears to be a server-side issue. When I run the Magento install locally, it works fine, and also when I move the install to the server it freezes all browsers again! Still not sure of what is causing this! – xvilo Dec 19 '16 at 10:56
  • Another small update for everyone else experience this. I have reuploaded the /js/ directory and everything seems to be working fine again. – xvilo Jan 9 '17 at 18:52
  • @xvilo I am getting the same issue on the server but it is working correctly on local system – Saphal Jha Aug 29 '17 at 12:52

I fixed this issue with increasing value of post_max_size in php.ini

If still get the issue, you should check the value of chunkSize in js/lib/uploader/flow.min.js

    Interesting! Thanks for sharing. The bug is still weird though. – xvilo Aug 29 '17 at 13:58
