I tested the page with:
computer: dark mode -> theme: auto
computer: light mode -> theme: modern dark
computer: dark mode -> theme: modern light
The page was normal, as in proper contrast for everything.
Can you please send me a screen shot (by email) of the page along with browser and theme setting?
Recently realized that a lot of people have their iPad/Tablet in dark mode and their theme is modern light and that cause the author pages to have light text. I fixed it.
I tried the various permutations for the page you reported but couldn't detect any problem.
I Forget to specify, it was on a Phone using Chrome in incognito mode.
But Even in firefox, when switching to phone either by the menu button or via the developer tools the problem is readily visible (it's even worse on a real AMOLED phone with low light...)
I think, the problem is the order of the css
@import url('/res/css/t-mobile-dark.css');
@import url(/res/css/contiphone.css);
dark should come after iphone.
Also I can't read the button My Stream #ccf over #BBE3C1
(That may be due to my red-green CVD.)
The help pages (on a phone) are also unreadable in dark theme.

The sub forum title is black on black, thus unreadable.
