Hi @Petr, Ah, it's at the top, a weird place for the "Add an Attachment" feature. I was always looking under this box we write comments in as that's where such a thing is in just about everything else. I guess that's a bugzilla peculiarity. I'll attach some files shortly that will hopefully help. > I will try to summarize for me: > 1. > 2. > 5. reporter's workaround: add extension=mysqlnd into /etc/php7/apache2/php.ini; > this is however not acceptable in general (will issue warning about duplicite > > extension loading, fx. on the php+apache+phpinfo() setup) Not quite. This works because it produces no error because you are adding it in only for Apache which is where it's getting left out. What should be the case is that it should not need to be added into the Apache specific php.ini file because it's already included from the files in the .../conf.d/ directory which covers all forms of use which just means CLI and Apache for the most part. > 6.
