Under Location Groups if the Group Name is empty and click Add, the locations dropdown is shown and you can add locations to the empty group. The group and locations in the group cannot be removed or deleted.
Network/Hosts Groups and Service Groups don’t allow for a blank group name
I can confirm the issue you mention. That is definitely a bug.
It would be good if you could raise this as a bug in the IPFire Bugzilla. Your IPFire People email address and password will act as your login credentials for the IPFire Bugzilla.
You can either remove the line for the group with no name, in which case the entry will no longer show in the WUI page or you can add a group name into the line as here:-
2,proper group name,testing with blank name,AO,Location Group
1,testing,ES,Location Group
That is what won’t work. I created the location groups and did not use them anywhere but without a location group name the entry only has the flag with AO Angola in my test case and there is no pencil or dustbin icon to edit or delete the location group.
@kat3 is correct that if you try and create a Service Group or a Network/Host Group and leave the Group Name empty when you create it then you get an error message telling you what characters are allowed for the name.
For the Location Group if you leave it blank then the code accepts that and saves the result but now the cgi code for the WUI page fails to display the action icons for that group.
Glad it worked for you. No idea why i put /var/run instead of /var/ipfire. That was an error on my part but glad you figured out the correct path. I have corrected my original post.
The fix for the problem has been merged into Core Update 179 which should come out for testing before too long.
