Gentlemen, Yesterday I identified an forgotten host in wui network / edit hosts and clicked the dustbin as recomended here: > **[Edit Hosts](https://www.ipfire.org/docs/configuration/network/hosts)** The wui-screen in my mozilla 140.7 turned to white and stayed white. I waited some time, but nothing happened. No menu any more. Mozilla’s reload-button didn’t bring it back. Mozilla’s back-button brought it back, but the host was still there. I tried to deactivate this host - same white screen as before. I tried another click on dustbin and no back or reload of browser’s page. About 5 hours later ipfire did it’s automatic reboot last night, but the host is still there, now 18 hours after reboot. How do I get rid of this host? Where is the host stored? It’s not in “hosts”-file ---

I can’t reproduce this issue. Can you supply some more informations? ---

Yes, of course. Host was in green.. “Forgotten host” means an host which is not connected to the network any more. system is raspi 4b, 8 GB, red, green, blue. Ipfire runs on 64 GB stick since about 6 months ore more. Permissions should be? ---

I deleted a host on my Raspberry Pi 4. The screen remained white for a few seconds, then the page refreshed and the host was successfully deleted. Check if there was an error in `/var/log/messages` at the time of deletion. ---

If the WUI page screen went white then it would also be worth looking in `/var/log/httpd/error_log` for messages related to hosts.cgi ---

`cat /var/log/httpd/error_log` contains startup and shutdown of apache last night and: “hosts datafile error at /srv/web/ipfire/cgi-bin/hosts.cgi line 166” `/var/log/messages reports firewall rules dropping traffic` but nothing about deleting hosts. ---

> [@firecherry](#): > > “hosts datafile error at /srv/web/ipfire/cgi-bin/hosts.cgi line 166” I was able to reproduce this error by modifying the file’s write access `/var/ipfire/main/hosts` ```auto [Mon Feb 16 21:35:01.814685 2026] [core:notice] [pid 2836:tid 2836] AH00094: Command line: '/usr/sbin/httpd' hosts datafile error at /srv/web/ipfire/cgi-bin/hosts.cgi line 166. ``` There was likely an error on your hard drive (or SD card) during the modification. Check the permissions on this file ```auto [root@ipfire ~]# ls -al /var/ipfire/main/hosts -rw-r--r-- 1 nobody nobody 271 Feb 13 23:23 /var/ipfire/main/hosts ```
