Hi all,

I just install Falkon browser to see how it works and fit in my KDE neon (just updated to the latest version).
Unfortunately once i actually try to run the browser it shows a white page. No options or any errors.

If i run it from terminal that is my output:

Code: Select all

I have absolutely no idea what is all about. Any suggests?

I presume you upgraded recently.
In which case you need to re-install Qt WebEngine and QtWebKit BaseApp - and then it springs back to life.
You probably don't need both of these - but I installed them anyway.
There was a cryptic message about re-initialising some software during the upgrade - but I didn't really understand it.
If anyone reading this can tell us what is going on, I'm sure we'd all be grateful.

Thanks for your reply.
How you actually do it?
