PDF invoice doesn't work after server redirection

-- HikaShop version -- : 2.3.2

Hi all,

I've created my website in local, then successfully transfered it on my web hosting (ovh).
First tests passed.

But then I linked the domain name to the right ftp folder, pdf invoice plugin is not working anymore.
Guest will receive an order confirmation by email but no pdf invoice.

Any idea?
Thanks

I've found my error: I was calling an image in invoice.php but did not specify the full url path.
Sorry for disturbing...
