Javascript errors when loading Virtualmin/Usermin

[mikerobinson]

SYSTEM INFORMATION
OS type and version	Ubuntu 22.04
Webmin version	2.111, tried upgrading to 2.202, error persists
Virtualmin version	6.0.1, tried upgrading to 7.0.0, error persists

The login page works fine, but after I log in to either Virtualmin or Usermin, I just get the page shell with the loading line at the top and the following error gets logged to my console:

Uncaught SyntaxError: Identifier 'platform' has already been declared (at bundle.min.js?2120700009999999999:1:1)

I tried updating the OS and rebooting the computer, but that did not work.

I assume that’s a conflict with some plugin in your browser, though I don’t know why/how that would happen.

What browser are you using? And what happens if you open Virtualmin in an incognito/private window with no browser plugins?

Would the network tab show where the conflict is happening.

Thanks Joe. That was it. The culprit was https://chromewebstore.google.com/detail/new-tab-start-page/mjfahldkpjhcnfbbmdhpjolcjpcfhcpj?hl=en. I’m actually wondering why that extension would even need page access since it’s involved in changing the new tab page, and shouldn’t need to execute code on other websites. Seems fishy to me. Anyway, thanks for pointing me in the right direction.
