Problem using sendFile with large ppx file

2017-09-22 18:19:18

I have a plugin installed to use a twig extension to download files after a form is completed. This is working fine and I've used it on a few sites. My issue is that I am trying to use it on a large 50mb .ppsx file and it doesn't seem to like it.

The form works sends the re-direct to the file processing file and it finds the file in the assets folder. However when it downloads it it only downloads a 1kb file.

Is there some sort of maximum file size limit or file restriction that would cause this to happen?
