Trying to switch an older M1 project to HTTP2, hosted under Apache 2.4.25
As soon as I enable Apache HTTP/2 (enable modules mpm_event, https and php7.2_fpm), the server serves all websites via H2 without problems, except the one with Magento 1.9.4.1. Without H2 it works fine with the same PHP as a module. Both the backend and the frontend generate the following error messages. Does anyone have an idea how this comes about? I've searched the whole web but haven't found anyone with a similar problem.
