I upgrade my version of Discourse yesterday & it broke on Brave (Ubuntu 20.04) with the following console error:

r.replaceAll is not a function

So I went through all the normal troubleshooting steps of turning off all of the plugins, turning off all browser extensions & doing a complete rebuild.

Even with all of the above I’m still getting a blank screen & the console error.

Today visiting https://meta.discourse.org/ using Brave desktop browser returns an identical error to my Discourse site:

Is anyone else experiencing this issue?

I’m seeing this error in logs starting yesterday’s upgrade in massive amounts.

r.replaceAll is not a function

3

What Brave version? v1.36.112 ?

4

Version 1.7.98 Chromium: 81.0.4044.113 (Official Build) (64-bit)

Which is the latest update (I think).

5

That one is quite old, and probably insecure by today: Release v1.7.38 · brave/brave-browser · GitHub

Latest is v1.36.112, try updating.

Interesting, thank you for the prompt!

I’ve become complacently used to having software on Ubuntu update automatically, especially the browsers & simply hadn’t checked that my version of Brave was updating.

I ran a manual update & it worked:

sudo apt install apt-transport-https curl
sudo curl -fsSLo /usr/share/keyrings/brave-browser-archive-keyring.gpg https://brave-browser-apt-release.s3.brave.com/brave-browser-archive-keyring.gpg
echo "deb [signed-by=/usr/share/keyrings/brave-browser-archive-keyring.gpg arch=amd64] https://brave-browser-apt-release.s3.brave.com/ stable main"|sudo tee /etc/apt/sources.list.d/brave-browser-release.list
sudo apt update
sudo apt upgrade brave-browser
