Your email is perfectly fine. Thanks for reporting and welcome to the

I was able to reproduce the issue. This is a bug on ox-hugo side.
`org-hugo--get-pre-processed-buffer' inserts text with
inhibit-modification-hooks bound to non-nil, which breaks
org-element-cache. The cache is enabled by default in latest Org, which
is why the issue revealed itself.

The fix on ox-hugo side can be made similarly to the new implementation
of `org-export--generate-copy-script' - ox-hugo needs to manually reset
the cache after silent changes in temporary Org buffer.

Could you kindly forward this message to ox-hugo devs?

If you are seeing some other packages (not ox-hugo) in the warning
backtraces, feel free to report them as well.
