Dashboard Evolution Graphics missing w/ apache2.4, php7 using php-fpm

I’m testing a migration to a new server doing an upgrade to php 7 with Apache 2.4 using php-fpm

to send the php requests to the handler I’m using this block in my http.conf :

    <FilesMatch "\.php$">
        SetHandler "proxy:fcgi://127.0.0.1:9000"
    </FilesMatch>

this works fine for just about everything except the images on the dashboard the show the evolutions.

if I manually add index.php it works fine, https://xxxxx.edu/piwik/index.php?module=

is there anyway to force this to be present or a change to the apache config I can make? any other ideas would be greatly appreciated as well…

thanks

I cross posted this to serverfault : Setting up php 7 w/ Apache 2.4 using php-fpm - Server Fault

looks like adding allowoverride indexes to my httpd.conf and then adding DirectoryIndex index.php resolved my issue…

figured I’d toss it back here in case someone else is looking to do the same thing…
