You mention that you also have this issue with the product thumbnails, does that mean you are using our Premium Templates extension? If that’s the case, please send us an email at [email protected] (make sure to include your license key), since this forum is for the free plugin only.
I’ve also tried changing the logo and i’ve tried adding a custom logo for invoice. All without success. Tried with PNG and JPG
Did you have “Test Mode” enabled while performing these tests? Otherwise it would use the previous logo for existing invoices!
In the preview browser window I can see the logo without a problem.
Are you referring to the developer HTML output? This is not fully representative for the PDF, especially in the case of images (and fonts), because to generate the PDF they need to be downloaded to your server. And the server could have security restrictions on downloading non-local resources (so anything loaded via the web over http/https, even if that’s your own site). Have you also tested with the HTML output option disabled altogether?
My configuration is in dutch and I can’t find; WooCommerce > PDF Invoices > Status > System configuration
In the Dutch version it is WooCommerce > PDF facuren > Status (last tab on the settings page) > Systeem Configuratie (near the bottom). It’s the same Status page where you enabled the “HTML output” option.
Let us know what you find!
