XF 2.2 Need help with server error "Uninitialized string offset: 96623"

[lg19]

Hi. Can someone please help me understand the server errors in my attached screenshots? I understand it has to do with my additions to extra.less, which I've corrected, so I'd just like to make sure it's OK to clear these now - I'm a CSS novice. Thanks!

You had some invalid markup in the template.

If the errors are no longer being triggered, you can delete them.

Great - that's what I figured and wanted to make sure. Thanks, Brogan!
