I look after the website airandmore.at, it is a wordpess site.
Now I ran into the problem that *.html and *.htm requests don´t work, for example do I get a "500 Internal Server Error" in case of https://airandmore.at/test.html
I disabled Yoast plugin (where I configured some redirects) and also renamed .htaccess. Problem still there.
In my eyes there should be a 404 in case this file is not available on the server or I should have the possibility to redirect certain (legacy) urls with *.html.
Any idea what could be the reason for the 500 error message in this case or how/where this could be changed?
