Error 500 System.OutOfMemoryException

I have a couple of buttons that when clicked simply download a .pdf file. They’ve been working fine for years. Here is the page: Holman Orthodontics - Bracing for Your Future

Now I get this error when a user clicks the button to download the .pdf.
{
“Message”: “internal error”,
“ErrorCode”: 500,
“Details”: “Exception of type ‘System.OutOfMemoryException’ was thrown.”
}
Any ideas? It’s not a very big website so I don’t think it’s really out of memory. I haven’t added anything new for a long time.

Hi @rachelward

You’d be best to submit a support ticket on this one.
(It’s most likely to do with the recent upgrade to v6.10)
