Hi,
The issue is only caused on nginx hosting, it is inside the file:
includes/buddydrive-item-actions.php
Function: buddydrive_file_downloader()
THIS:
while ( ob_get_level() > 0 ) {
@ob_end_clean();
@ob_end_flush();
}
BECAME THIS:
#while ( ob_get_level() > 0 ) {
@ob_end_clean();
@ob_end_flush();
#}
This was the approach that works for nginx also.
