Thank you. I think the problem is in DOMPDF library (in the default fonts)

Yes, i think so. Thans for your answers. Will contact with my network admin to enable another non-secure port forwarding.

@jonathan, i’ve tried do that. Without positive results. A strange thing that phpMyAdmin works fine, and admin part of wordpress too. I do not need any security, but some another site on that server need for it. And i’ve got the only one external port 9443 which is redirected to internal port 443.

Yes, of course.

unfortunately it doesn’t work too. I mean it works with the same result. I’ve tried both https://x.x.x.x:9443/wordpress and https://9443/wordpress
