eCart - random blank order emails
I have eCart running on a site - www.earlyyearsdirect.com - for a few years now.
Occasionally something happens like this: the order receipt is received by email, followed by another 5 which are blank... see attachments.
Bit of a weird one as it doesn't happen every time. All emails have the same SagePay order no.
Any ideas to get me started ? Every time I test it works fine.
Thanks for your help as always
