I had this strange issue again, but this time I will allow you to see it before I resave the post which fixes it.

So this url is broken
https://style-review.com/you-blog/entry/primark-is-a-zoo

Its some 500 error.

If I resave (maybe even just open the post in the backend) the post it will magically start to work. A normal working post can be found here to show you the site is working.

I dont want to fix this blog post (YET) as I would like to know why it is happening and if you have some idea as to why?

Thanks
