Version 5.15.1, on WordPress 5.2.2.
Transferred our site to a new host, and everything seems to be OK -- I can search contacts, navigate various system settings, etc. But the main navigation menu is gone. I've double-checked that it should be replacing the WP menu at the top, and I have run 'Cleanup Caches' and 'Reset Paths.' I've also installed the CiviCRM Admin Utilities plugin and reset the menu with this, no no avail.
'Reset Paths,' however, gives me the following feedback -- is this a clue?
Beginning site move process... WARNING: The setting (userFrameworkResourceURL) is overridden and could not be reverted. Template cache and upload directory have been cleared. Database cache tables cleared. Session has been reset.
As far as I can tell, the userFrameworkResourceURL is correct anyway. Where else should I be looking?
