Issue Summary

When we try to attach a file that exceeds the attachment maximum size limit in the Confluence site in the Attachments macro, nothing happens but the spinning wheel keeps loading forever.

Steps to Reproduce

1. Navigate to Settings > General Configuration;
2. Edit it and set the attachments maximum size to 100MB, for example;
3. Create a new page;
4. Insert the Attachments macro, then publish the page;
5. Drag&drop or search for a file in your computer that is higher than 100BM to try to upload in the page.

Expected Results

A warning message is thrown saying the file exceeds the maximum size set in that Confluence instance.

Actual Results

Nothing happens - the spinning wheel keeps spinning forever.

Notes:

• You can use this command (on OSX or Linux) to generate a 300MB file: dd if=/dev/zero of=file.txt count=1024 bs=300000

Workaround

You can either reduce the size of the file or engage one of your Confluence admins to increase the maximum size limit.
