I had a similar error, which was fixed by adding:
... in the
apps/[app-name]/conf/httpd-app.conf file. This is because, in my case, an
.htaccess file wants to use rewrite rules, that are not allowed with FollowSymLinks AND SymLinksIfOwnerMatch turned off.
If your conf file already has a line with
Options ..., you can just add
FollowSymLinks to the list of options. You could end up with something like this:
Options Indexes MultiViews FollowSymLinks
