datadome.co white page

Post by Gemmaugr » 2026-05-08, 11:30

I saw another "interesting" subject (https://datadome.co/threat-research/how ... rprinting/) and when I tried to view the site in question it said to enable JS (which was enabled) and to disable adblockers. I had to allow some new non-CF/google captcha in eMatrix, and this resulted in a white blank page (nothing blocked in uBO and everything allowed in eMatrix). I even tried to disable eMatrix and uBO completely, but it's still just white.

Error console:

@ Gemmaugr

I clicked on the link you provided and I had no trouble going to the site and the site rendered properly. One thing though. At the far left of my Status Bar, I think my uBlock Origin is blocking something named, "userway". Anyhow, below is my screenshot.

Turns out it was actually PureURL that blocked the captcha:

Code: Select all

[PureURL:]Original request: https://geo.captcha-delivery.com/captcha/?initialCid=(removed)
Cleaned request:https://geo.captcha-delivery.com/captcha/?initialCid=(removed)
Which I found in the Developer Tools Error Console, and not the F12 error console. Thanks for pointing me in the right direction though.

How come the original and cleaned requests are identical then?

I was the one who put (removed) there, because the initial strings of random letters and numbers were just so large (and might contain some identifying parameters, perhaps).

The full entry is;

Good, it's been years since I touched the code and was concerned it wasn't working properly :)
