This means that your server doesn’t allow URLs to be used, you have to use an absolute path to the image on the server. More information: https://docs.wpovernight.com/woocommerce-pdf-invoices-packing-slips/insert-images/
You could also ask your host to enable allow_url_fopen
, but most hosts have disabled this for security reasons, so using the full server path may be your only option. If you don’t know the server path, you can check the Status tab of the PDF invoice settings, for example if you take the Central temporary plugin folder
, it should look something like this:
/home/public_html/cristalit.de/wp-content/uploads/wpo_wcpdf/
You can copy paste the bit up to wpo_wcpdf
and combine this with your URL:
/home/public_html/cristalit.de/wp-content/uploads/2016/12/Fu?zeile.png
(these are just examples)
Hope that helps!
