Sidebar content width has reduced & I can't change it back

Hi hoping someone can help!

I've been using the SQSP Themes sidebar for the past year on my blog pages - and it's worked great. No issues with the width content spacing (see Side bar 'Hey There' image as example).

Recently, I changed the sidebar page content but I'm not sure why the content is now super narrow? It seems ok on mobile view but Desktop is super skinny.

I may have changed the site width at some point a while ago but I've tried adjusting this again but it doesn't change the sidebar content width. Super frustrating!

I haven't changed altered any of the original plug in CSS.

Any ideas?  Thanks in advance 🙂

EDIT: Reuploaded the plug-in CSS files and it's refreshed itself - and spacing is all good again.
