My web space provider performed a few server upgrades recently. They cause(d) problems with my MediaWiki and my WordPress installations. Before contacting their helpdesk I upgraded my MediaWiki installation to 1.31.1, and I also fixed an issue with my …/skins/common/images/wiki.png . Bad enough I did not take a note, whether my …/wiki.png problem started getting shown with the web space provider’s server upgrades. Now I am back to the default logo, and everything is fine again.
From that (actually quite old) article I somehow got the impression, some SUNRISE setting in my wp-config.php could be in my way. I do not have any sunrise.php, and I just uncommented the resp. setting, and everything was fine.
I guess I had once needed that setting, but bad enough I had not left a comment as an explanation.
Maybe WordPress (more or less) silently performed some upgrade itself, and sort of caused the problem “itself”, but I don’t know. Just mentioning this possibility here for completeness.
The Faust story should actually be quite sad, but this show was somehow a rather refreshing French thing as opposed to the German operas I saw recently. Don’t get me wrong! All of them excellent music, but this French thing was really more “colourful” and enjoyable.
