This is something that keeps coming up after each release for a number of users and is almost always related to caching in your local browser. These issues fix themselves magically after some time. To fix it now, try Ctrl + F5 or Crtl + Shift + R (or whatever the Mac equivalent ist).

[echaritos]

Can confirm this is client based. Ctrl + F5 fixed my issue

[JobbeDeluxe]

That will not work either. I tried from many browsers and devices.

[DL6ER]

It is very strange that it loads partially for you (as all data is requested from the same source). Can you confirm that you have the most recent version of FTL ?

pihole-FTL version

Maybe you can try a restart of FTL in case the binary got updated but the service wasn't restarted

sudo service pihole-FTL restart

[JobbeDeluxe]

:~ $ pihole-FTL version
vDev-437af07

I have restarted the ftl service and the server as well. No change.
Bevor the update it was shown correctly.

[echaritos]

Can you confirm that you have the same problem when viewing the webpage on a PC/Mac? The screenshot seems to be from a mobile device

[JobbeDeluxe]

The first is from a laptop.

[JobbeDeluxe]

But it seems to be a client problem. I just installed opera to be sure....
And there it will be displayed correctly

Before I was used chrome on both devices.

[DL6ER]

Hmm, could you try the Request Desktop Site option on your Android device?

Which browser are you using on your Desktop? We test Vivaldi, Firefox, Chrome on Linux (partially on Win) as well as Safari on Mac during development, all in their most recent releases (regular releases, not development releases) and haven't seen such an issue.

[JobbeDeluxe]

I tried Chrome on Linux and android.
The same problem on Android with desktop view.

[DL6ER]

Okay, can you please open the developers tools on Chrome/Linux (press F12) and look for errors in the Console?

[JobbeDeluxe]

Right now I'm going to lunch. I will do in half an hour.

[steffanson]

We test Vivaldi, Firefox, Chrome on Linux (partially on Win) as well as Safari on Mac during development, all in their most recent releases (regular releases, not development releases) and haven't seen such an issue.

I had the very same issue yesterday after updating from 3.1.4 to 3.2 with the FF 57.0.1 and Chromium 62.0.3202.94 on Linux.

The error console did not reveal any problems to me; however what helped in my case was flushing the logs (on the terminal, as the button on the website is broken right now). After doing that, it took about a minute until the statistics came back.

@JobbeDeluxe: Maby you can test it by moving your old logs to a backup folder?

[JobbeDeluxe]

I tested on FF, this will display the Dashboard, longterm data is not avaliable, but this can be a problem of the log flush maybe.
On Chrome is no error in the console

[DL6ER]

What does http://pi.hole/admin/api.php tell you?

[JobbeDeluxe]

{"domains_being_blocked":106012,"dns_queries_today":4547,"ads_blocked_today":2420,"ads_percentage_today":53.221905,"unique_domains":302,"queries_forwarded":1174,"queries_cached":951,"clients_ever_seen":18,"unique_clients":18,"status":"enabled"}

Seems to be OK

[DL6ER]

Seems to be OK

I agree. Could you try executing the following in your Console while you are on the dashboard?

updateSummaryData(true);

[JobbeDeluxe]

->updateSummaryData(true);
<-undefined

that what i get.
but the same i will get on FF

[Mcat12]

Did the summary stats update?

[JobbeDeluxe]

Nothing changed

[Mcat12]

What versions of browsers are you using?

[teapleasenosugar]

I had this problem. To fix, you have to clear the cache in safari. Remember that iCloud will sync this, I cleared the cache (for my piholes IP address) from Mac OS safari, reloaded the page and all is well.

[JobbeDeluxe]

I cleared my cache on mobile device and reloaded the page. This fixed the problem on my mobile, so I think it will do on laptop as well

[adi2k5]

I had the very same problem with data not showing, but it turned out that graphs were not displayed due to SELinux, after fixing this graphs are OK. But I can't get stats to work, clearing caches etc is not helping at all, all what I get is "---" for each field. When I'll go to api.php, it gives

{"domains_being_blocked":2847358,"dns_queries_today":10331,"ads_blocked_today":4512,"ads_percentage_today":43.674377,"unique_domains":1024,"queries_forwarded":4606,"queries_cached":1172,"clients_ever_seen":1,"unique_clients":1,"status":0}

One thing that I noticed that might be causing the issue is this warning in php log:

PHP Warning:  number_format() expects parameter 1 to be float, string given in /var/www/html/admin/api_FTL.php on line 39

[vivasmaq]

This morning i updated my version to the last one and i had this same dashboard blank(---) indicators on opera browser. I enter this issue and then reload the dashboard with ctrl+f5. Nothing changed. Luckly I have a firefox that i never use installed on a computer next to me. Work Great. I confirm, this is a client side browser cache related issue. Just seat tigth, wait longer enough so Opera make his own cache clear task

[Mcat12]

@adi2k5 Have you modified that file, or are you on the latest version? It does not appear to call number_format:
https://github.com/pi-hole/AdminLTE/blob/master/api_FTL.php#L39

[adi2k5]

@Mcat12 No, I haven't. To be sure I just wget copy from github and it's still the same. I've done some testing, and it seems that this warning comes from https://github.com/pi-hole/AdminLTE/blob/master/api_FTL.php#L55, as it stopped when I removed 'floatval()' from that line.

And yes, I'm on the last version:

pihole -v
Pi-hole version is v3.2 (Latest: v3.2)
AdminLTE version is v3.2 (Latest: v3.2)
FTL version is vDev-437af07 (Latest: v2.12)

[Mcat12]

What is the output of this command?

echo ">stats" | nc localhost 4711

[adi2k5]

echo ">stats" | nc localhost 4711
domains_being_blocked 2852587
dns_queries_today 8627

[DL6ER]

@adi2k5 that looks fine at first glance, can you quote the error you have seen in lighttpd's log file?

[adi2k5]

That's the point, there's no errors in logs, just php warning mentioned above

[17-Dec-2017 11:58:49 Europe/Warsaw] PHP Warning:  number_format() expects parameter 1 to be float, string given in /var/www/html/admin/api_FTL.php on line 39

Except this warning I don't see other errors nor problems, access.log have only this

192.168.1.1 my.domain user [17/Dec/2017:11:58:50 +0100] "GET /admin/api.php?summary HTTP/1.1" 200 174 "https://my.domain/admin/index.php?login" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.97 Safari/537.36 Vivaldi/1.94.1008.34"

Strange is that all is working as it supposed to work, charts, stats of top blocked domains etc. All except this 4 'small blocks'.

[DL6ER]

@adi2k5 Please open a separate issue on https://github.com/pi-hole/AdminLTE/issues to keep things clear in here, I suggest to use the title number_format() expects parameter 1 to be float, string given

One question you could already answer therein is: How do you format numbers in Poland? E.g. we use . as decimal separator in English, but , in German. This might be a locale issue within PHP we haven't thought about yet.

[DL6ER]

@JobbeDeluxe @vivasmaq Is your issue resolved by now?

[JobbeDeluxe]

Clear the cache have solved the problem on all my devices

[adi2k5]

We use comma , as decimal separator, and thin space as thousands groups separator, this examples of fortmatting in some countries might be useful: https://docs.oracle.com/cd/E19455-01/806-0169/overview-9/index.html

[dschaper]

@adi2k5 Please open a new issue as DL6ER has requested.

[jacobsalmela]

Seems the OP's issue is resolved. Closing.
