On Ubuntu 18.04, apache 2.4.29 all patches for both applied. Did an upgrade today to 5.8.0. The header civi nav menu isn't displaying. Installed 5.8.1 to make sure it wasn't something cooky, still no menu.
I've checked permissions for WP. I've checked that the path to the file is kosher, and it exists just fine. I've done the cache and path reset inside civi.
Error log in apache shows:
