Lightread used to work well on my system.

Now I just get a blank window when I launch the application.

It has the menus at the top.

I have uninstalled and re-installed, but still get same behaviour.

Unlike on know from an other very common operating system, reinstalling software is rarely a problem solver on Ubuntu.
In your case there might be a problem with the user data, which is stored seperately from the installed application. You should erase the user data since nearly everything except of a few setting and the login will be redownloaded from Google.

Unluckily Lightread has a very intrasnparent way to store data. It uses a share database storeage for all webkit based application. But such apllications are not very common, so, you should go into ~/.local/share/webkit/databases and see if there is only one .db file in the subfolders.

If there is only one, remove the whole databases folder while Lighread is not running.

If is more than one .db file in subfolder it is more complicated:
 - make sure you are in ~/.local/share/webkit/databases
 - run:
   sqlite3 Databases.db
 - run (inside sqlite):
   SELECT origin || '/' || path FROM Databases WHERE name='lightread';
 - keep sqlite open and delete the file the last command returned
 - run (in sqlite):
   DELETE FROM Databases WHERE name='lightread';

This should reset all the user data.

I can't seem to find the folder.

Even though I am logged in as admin two folders "lost+found" "root" and a file called vmlinuz have big red crosses and tell me that I can't display the contents because I'm not the owner. I also can't change permissions on them.

If you want to use the file manager, which is fine when there is only one database file, you have to press Ctrl+H to see the hidden files. Files starting with a dot are hidden from the user. ~/ is a shortcut for your personal home folder. So you will see a folder called .local in your home after pressing Ctrl+H.

You the second way, you have to use the Terminal you can just cd into the folder by copying the name:
cd ~/.local/share/webkit/databases
And list the content with "ls".

Thanks for all your help, both with the application, and the running of Ubuntu in general.

Appreciated!
