Vertical navigation

Can anyone explain to me why my plugin left navigation is now overlapping and how I can get it to stop doing that? It has happening on all pages. Please see screen capture to illustrate.

Thank you!

Did you just upgrade to Omeka 2.5?

It adds a wider admin view for high resolution screens, but you might need to “hard refresh” and/or clear your browser cache for it to work properly if you have the old CSS cached.

Thank you, that was the issue.
