Hello,

The error problem is written in the error message. The write permission for the folder '/home/cmflv/public_html/administrator/components/com_vmeticket/assets/ean_codes/' and user apache aren't allowed. You must allow this the write permission for this linux user.
If the image can't be written, then can't be displayed in the tickets PDF file.
If you don't know how to configure it, let contact your server administrator or you can buy a payed support.

Yours faithfully, PeDu.
