Since Joomla 3.8 one gets the option to remove the article numbers from url's which is great as it means that joomla is learning to be as neat and seo friendly as wordpress. It does pose some teething troubles such as the following url
https://cambs.eu/blog/entry/101-inspirational-websites-for-design-or-use-comment-to-suggest-a-site
Can you test your latest with joomla latest using the new url format and report back any issues thank you.
In the above url the 101 is getting stripped out and yet still failing (perhaps because it is not a normal joomla article)
