These permissions are the same at my machine.

ganglia:~#  ls -la /var/lib/ganglia-web/dwoo/
insgesamt 16
drwxr-xr-x 4 www-data root 4096 Jun 27 12:37 .
drwxr-xr-x 4 root     root 4096 Jun 27 12:37 ..
drwxr-xr-x 2 www-data root 4096 Jul  7  2016 cache
drwxrwxrwx 3 www-data root 4096 Jul 27  2015 compiled


I tried further, purging and reinstalling ganglia-web and apache did not
help.
What solved the problem was enabling all modules with

   a2enmod
Your choices are: access_compat actions alias allowmethods asis
auth_basic auth_digest auth_form auth_kerb authn_anon authn_core
authn_dbd authn_dbm authn_file authn_socache authnz_fcgi authnz_ldap
authz_core authz_dbd authz_dbm authz_groupfile authz_host authz_owner
authz_user autoindex buffer cache cache_disk cache_socache cern_meta cgi
cgid charset_lite data dav dav_fs dav_lock dbd deflate dialup dir
dump_io echo env expires ext_filter file_cache filter gnutls headers
heartbeat heartmonitor http2 ident imagemap include info
lbmethod_bybusyness lbmethod_byrequests lbmethod_bytraffic
lbmethod_heartbeat ldap log_debug log_forensic lua macro mime mime_magic
mpm_event mpm_itk mpm_prefork mpm_worker negotiation perl php7.0 proxy
proxy_ajp proxy_balancer proxy_connect proxy_express proxy_fcgi
proxy_fdpass proxy_ftp proxy_hcheck proxy_html proxy_http proxy_http2
proxy_scgi proxy_wstunnel ratelimit reflector remoteip reqtimeout
request rewrite sed session session_cookie session_crypto session_dbd
setenvif slotmem_plain slotmem_shm socache_dbm socache_memcache
socache_shmcb speling ssl status substitute suexec unique_id userdir
usertrack vhost_alias xml2enc

and enabling all of them solved the problem.

I'm not sure which of them I really need, but suspect that there is a
missing dependency on either to php7 or gnutls module.


Thanks for considering,
