One of our users is encountering the following error when trying to import a payment file.
"Upload did not complete within the 65 seconds time limit.
The maximum file size is 350MB"
Size of the file is 
Can someone please advise where we can set the time limit?
Please note that this isn't the biggest file that's ever been imported and a bigger file imported with no issues in the past.
It's ME for us so there's a deadline for tomorrow to get this file imported.
Appreciate any help someone can give!
Many thanks
