[Plugin: Dropbox Simple Upload] Large files not working

Hi there, I’m having issues uploading large files via the Dropbox Simple Upload plugin. I’ve modified both my php.ini and wp-config.php files to allow me to upload 1000mb files (previously 64mb). I’ve tested this out by uploading a large media file from my WordPress dashboard, which worked fine.

When I try and do the same from the simple upload form, it gets to 100% and the screen refreshes. There’s no message (which I added in settings) to say it’s uploaded correctly and there’s no message to say it has failed. No file is received in Dropbox. I’ve tested it with files up to 20mb and it works fine. Any ideas why it isn’t working and why I’m not getting any sort of message?

Curiously, I also tried the Sugarsync plugin that is mentioned in another post and the exact same thing happens. The upload gets to 100%, the screen refreshes and then nothing. Again, smaller files are fine.

If you want to have a look at the page on my site and give it a go, it’s https://www.productlondon.com/?page_id=255

The idea of the upload form is to allow large WAV files to be uploaded.

Thanks for any help.
