It looks like the router log is showing those plugin upload events:

But I’m not seeing any reason in this log as to why it is failing.

There might be something in the more general Local log – Can you please provide that? See this Community Forum post for instructions on how to do so:

Otherwise, it might be a good idea to reach out Divi to see why this isn’t working despite the various other WorPress folders being able to be written to disk by WordPress.
