Expected Behaviour:
When i on the Mainpage of pihole i see the query diagram and stats of blocked ads
Actual Behaviour:
i see nothing
Extra informations
i use nginx as webserver
For me, this helped:
pihole -g -r
no i tried it already but no change the log says it create everythink correct, but under pihole -d the log say the gravity.db does not exists under /etc/pihole/, when i look at this path it exists 
<
the new debug token after a clean install of pihole
Same problem here...
> May 11 08:56:17 dnsmasq[15245]: bad address at /etc/pihole/gravity.list line 426705
With the command
awk 'NR==426705' /etc/pihole/gravity.list
you can check that line.
Thanks, but my hole pihole.log looks like this
That's why I think it's a problem with the gravity.list
I fixed the problem by setting the permissions of /etc/pihole to 777 and than made pihole -up again
nginx is not a supported server for the Pi-hole web admin page. There is an unsupported user guide that may have some information that can help you:
I'm experiencing the same issue. Also, FTL won't update from 4.3.1 to 5:
E: Unable to locate package php5-xml
E: Unable to locate package php-intl
I already setup correctly by this guide
I have the same problem.
And also errors on the GroupManagement-Groups page, Network page and others because Ajax content cannot be loaded. Does that work for you?
http://192.168.1.2/admin/api_db.php?network&_=1589217731596 -> Error 500
http://192.168.1.2/admin/scripts/pi-hole/php/groups.php -> "Not allowed (login session invalid or expired, please relogin on the Pi-hole dashboard)!"

Yep I agree
Hi guys, everyone who did not choose to install Lighttpd within Pi-hole installer needs to do:
usermod -aG pihole www-data
apt install php-intl # Respectively the package matching your PHP version, like php7.3-intl
I just got the idea to view the error log from the webserver:
[Mon May 11 20:33:50.704422 2020] [php7:warn] [pid 3039] [client 192.168.1.60:56525] PHP Warning: Use of undefined constant SQLITE3_OPEN_READONLY - assumed 'SQLITE3_OPEN_READONLY' (this will throw an Error in a future version of PHP) in /var/www/html/admin/scripts/pi-hole/php/database.php on line 61, referer: http://192.168.1.2/admin/network.php

Then I checked if php-sqlite3 is installed, which was not the case. After a webserver restart it worked again.
Edit:
New problem: When I want to edit the groups While executing: **attempt to write a readonly database**
Please open a new topic for this problem, so the existing topic for the original issue can continue.
The issues have the same source, hence I would not separate. In case of OP it is expected since Nginx as webserver means that INSTALL_WEB_SERVER=false is set which again means that the installer/updater does not add www-data to pihole group, preventing database write access, and no PHP modules are installed, leading to missing SQLite and intl modules. Although in case of SQLite it is strange since this was used/required before already 
.
Micah, respectfully, we'll handle our support the way we prefer.
I have tried but no change in view and errors by loading the query log or group management.
I already installed sqlite for php7.x in the past.
