Hi Eva,
Thank you again for your fast response! To give you a simple log, I have done a clean restart, then tried to access the Products Feed Pro area in WP admin, and displayed the desperately empty list of countries. Here is the log, below. The MPM-related issue will be fixed later, it’s easy but requires to be done carefully, which we can’t currently do ??
You can also see 1 simple trace that we have added…

[Fri Jul 27 11:38:47.244318 2018] [http2:warn] [pid 21716] AH10034: The mpm module (prefork.c) is not supported by mod_http2. The mpm determines how things are processed in your server. HTTP/2 has more demands in this regard and the currently selected mpm will just not do. This is an advisory warning. Your server will continue to work, but the HTTP/2 protocol will be inactive.
