It almost looks like something could have gone wrong during your particular update, or the updated dependencies are not being loaded. There are no references to that particular gif in V3+.
I would recommend attempting to re-update.
What system/browser are you using? This has been tested on Mac/Windows in Chrome, Safari, Firefox, IE (9+), and Opera.
Hmm. ..yup, a re-install fixed it …odd, ..sorry for the sensationalist post in that case …all good and thank you for the quick response.
will likely delete this as you will get my reply in your inbox …not fair to leave it on what is one of my top 10 plugins.
No worries… glad that fixed your issue.
Coming back to this …I realised what is going on …on auto-update for some reason it is not updating the CSS,…which breaks the formatting …even on a clearing of cache …but if I then delete and re-install the plugin, it is still off, …THEN clear the cache ..it sorts itself out.
In case anyone else has the same issue.
Or not …when I did the last site, it remained broken, ..when I opened the nested pages css through the inspector, it opened this url:
https://www.thedrhcollection.com/wp-content/plugins/wp-nested-pages//assets/css/nestedpages.css
..notice the double // …of course switching that to a single changes the file loaded in:
