Opera keeps forcing dark mode on localhost

I'm working on my first website with html, node, etc.
Since I don't know what I'm doing I rely heavily on ChatGPT, so I'm sorry if this a very stupid mistake. But I don't acctually think it has something to do with my code. Here is the problem:

I run a node server (server.js), then I can see my website at http://localhost:3000

using edge as browser all colors of the website are as I would expect. Using Opera they are all darker or i.e. black text got turned in to white. So it sounds like Opera is forcing a dark mode.
It wasn't allways like this. I even think I misclicked something when I wanted to cklick on "analyse element". I think it was then that it started showing the wrong colors. But I don't know what I clicked and also not how do undo it.

I have the theme set to dark for Opera and I would like to keep it like this. I don't have "force dark site" enabled. Chaining the theme to light did have an effect either.
Also disabeling "Enable Force dark theme on pages from Settings and Easy Setup" and "Auto Dark Mode for Web Contents" under "opera://flags" had no effect either.

Also I don't knwo if that is related but sometimes it still used some old chached version of my html, css, etc files even after reload. I this cases I used the incogni winodw. But for the dark mode problem even restarting my pc did not help.

Any cule what is going on?

Okay I mangaged to solve it.

Somehow I managed it to aktivate force dark mode only for http://localhost even though the feature "force dark mode" was turned off. Under opera://settings/content/forceDarkMode I was able to delete it again. Now everything is back to normal.

I'll leave the post here for others that might have the same problem
