Probably it is just me being too stupid (or too tired, it is way too late to be working 😉) but I just installed LogViewPlus on my laptop and the Sidebar on the left, showing Log Files & Filters is not visible when a log file is opened.
I can not find any option to enable that.
On my desktop computer it is visible.
I know you can "fold" it, so there is only a small gray bar, but that is not the case here. It is just completely gone.
What can I do to get that sidebar to show up?

After some investigation, I believe this is due to corruption in the layout.xml file.  Please make sure LogViewPlus is not running and then delete the file at: 

%AppData%\LogViewPlus\layout.xml

That should resolve the issue.  It is not clear why the initial corruption occurred, but it is possibly do to a versioning upgrade issue in a third-party library.  I have updated LogViewPlus to be more aggressive in removing this file if an issue is detected.  That won't prevent the issue, but it should resolve it automatically after an application restart.

Hope that helps,

Toby
