I'm trying to create new QWeb reports in Odoo 10 Community, but for some reason (locally speaking), when I download the PDFs and try to open them, they no longer open. The document keeps loading, but nothing opens. I've tried with several browsers and in incognito mode, but nothing works.

1: I've already added the report.url to the system parameters.

2: I've already added the web.base.url to the system parameters.

3: For version 10, I'm using the wkhtmltopdf 0.12.5 library (with QT patch).

4: I can open the other default reports (e.g., sales, invoices) without any problems, but I can no longer open the new reports in PDF format. However, I can see the structure if I change the format to HTML.

Any idea why this might be happening?

Thanks.
