SugarPHPMailer encountered an error: Could not access file: upload://

Hi,
I have troubleshooting with SuiteCRM 7.11.2
when I want to send email to a target-list it works well, but no attachment.
I have tried to attach directly(choose file) when writing message in the campaign, and choose document (even change rights on the file 777) but still doesn’t work
Log file message is: SugarPHPMailer encountered an error: “Could not access file: upload://1e01ac38-1145-9f4f-146b-5c9e99a172d4”
Sorry I believe this is a well known problem but I found any solution.
(attachement worked fine with old sugar application)
Can somebody help me ?
Thank a lot

Hi,
I have installed another suitecrm, last version, for testing.
It doesn’t work as well
Can somebody just tell me whether it is just normal (not allowed to send attachement) or if it should ?
Thanks !

Hello! I have the same problem; I did the test in versions 7.10.10 and 7.11.4 and I got the same errors mentioned above. Is it a bug of the program? Could someone solve it? Thank you!

Version:7.11.13

Sending PDF from Quotes module. The email looks fine and attachment is there before sending. But no attachment is delivered to the recipient.
