Getting error -200 when any member tries to upload any files larger than 460mb, but when the server admin user uploads a file on any size locally to server it works.

Any ideas?

PHP memory and upload file limit settings allow up to 1GB.

Issue resolved.

PHP settings were out of whack, due to a change between IPS 4.5.x and 4.6.x.

Reverting the PHP settings back to recommended values, fixed the upload errors.
