Inner.html starts downloading when loading a page?

I have a strange issue. When I go to a page like this: Music I get a popup in my browser that asks if it’s alright to download a file. If I say yes, it downloads a file called “inner.html”.

Anyone knows why this is happening? Is it a config error somewhere? I am self-hosting and have recently updated to Version: 6.55.0. Using the docker install method.

Any form of assistance is appreciated :slight_smile:
