Admin console not displaying correctly

[PromoFaux]

@th4t9uy commented on Fri Jan 22 2016

Set up PiHole on a fresh Raspbian Jessie LITE install on a RaspberryPi Model B.

However, not long after set up the admin console has started looking like this http://i.imgur.com/1RhcVuC.png

I have tested it in Firefox and Internet Explorer, I get the same result in either browser. On the RasPi so far all I have tried is restarting the lighttpd service.

Okay, thanks for the report, we'll take a look at it...

@dschaper commented on Fri Jan 22 2016

Do you have anything for your blocking page, or did you leave it with the stock blank html? And can you grab a page source? Thanks!

---

@PromoFaux commented on Fri Jan 22 2016

Do you have any extensions installed? Ad block plus/Privacy Badger etc? If so.. can you try disabling them and refreshing? Thanks

---

@jacobsalmela commented on Sat Jan 23 2016

I haven't seen this one yet, but try another browser and/or disabling the extensions.

dschaper: I left it with the stock html, the only thing I changed during the initial of Pi-Hole setup was settting at a static IP address and enabled IPv6 blocking. Page source is as follows: http://pastebin.com/9n0SHn3Q

PromoFaux: I did initially have UBlock Origin and Disconnect Firefox addons enabled. Both have since been disabled but it didn't help unfortunately.

jacobsalmela: I have tried Firefox and Internet Explorer, the latter I doesn't have any extensions/addons running. I have also since tried Chrome from my phone but again that does not display correctly.

Thanks for the update. Can you do an ls -lac /var/www/html/admin and
ls -lac var/www/html/admin/css

Those look good. How about a cat /etc/lighttpd/lighttpd.confplease?

That all looks good. Since you haven't made any changes to the configuration, would you re-run the curl -L install.pi-hole.net | bash command again and try a new install. This should just install over your existing configuration.

@th4t9uy commented on Sat Jan 23 2016

All back to normal! http://i.imgur.com/XTM0QBL.png

Thanks for all your help guys

@dschaper commented on Sat Jan 23 2016

Great! Thanks for using the Pi-Hole!

@ecaron commented on Thu Jun 09 2016

I encountered this tonight too. I found the problem was a bunch of 0 byte files in /var/cache/lighttpd/compress/admin. I just rm -rf'd the directory and restarted lighttpd. Problem has not come back, yet.

I'll keep an eye on it happening and update this thread if I find more. But thought this might be useful for people before proceeding to perform a new install.

---

@dschaper commented on Thu Jun 09 2016

Thanks for the report. Let us know if it does come back. (How'd you even think to look at the cache!)

---

@ecaron commented on Thu Jun 09 2016

How'd you even think to look at the cache!

Just following the rabbit hole. I was disabling parts of the /etc/lighttpd/lighttpd.conf file and things started working when I commented out the compression lines. Once I nuked the directory and removed the comments, some files started reappearing in the cache directory but not as many as before. The hunt continues! (I'm also on a Pi B, so maybe it has to do with not enough processing power to run the minifiers?)

Well I have it running on a Zero, with a ton of empty overhead to grow into. It does take about 5 seconds or so to start rendering and 20 seconds until complete graph rendering and no more spinners. I wouldn't think the 300MHz boost that the Zero has over the B+ would make that much impact?

@ecaron commented on Thu Jun 09 2016

Excellent point. I apologize to the Pi for thinking it unfit:-) I'll keep
figuring out how to investigate the cause.

👍 I sent my 256MB models to greener pastures... If you do come up with a cache bug, open up a new Issue thread for it and we'll see if it's something that is upstream or a config issue.

@luebbe commented on Thu Aug 11 2016

Hi Folks,
I had the same issue today. A fresh install of pi-hole on a vanilla raspbian, Raspberry B.
Everything worked fine until after an hour or so, the admin page looked almost like in the original posters screenshot.
I checked the config files, went through the re-install, deleted the cache, but nothing helped.
Only when I commented out "mod_compress" in the server.modules section of lighttpd.conf and restarted lighttpd, everything worked as expected immediately.

I'm closing this since there was no contribution since August 2016 and the web interface has changed a lot in between.

Feel free to reopen this issue if the error persists.

For anyone else who ends up here:

I got the same admin screen showed by @PromoFaux in the original post in this thread a couple days ago.

My problem started when the root filesystem on my pi filled up.

After freeing up space I cleared the admin cache as described by @ecaron on Thu Jun 09 2016 and the admin console returned to normal.

Suggestion to Devs: clear the cache when pihole is repaired, reinstalled, or upgraded...
