I’ve experienced the same issue as wasmachinekeuze, did you ever find the culprit?
my structure is
domain.com/blog/category/postname/ (standard)
with decategorizer its:
domain.com/blog/postname/ (nice and clean)
so every 24hrs it goes back to standard, the temporary remedy fix is to de-activate decategorizer and re-activate it, this seems to reset somthing and makes it work again.
When it resets back to standard all the links still point to domain.com/blog/postname/ but the path just doesn’t resolve.
these are the plugins i have:
