Magento 1.9.2.4 media uploader freezes browser

Question

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.

Answer 1

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
