Ok so I removed one of the conflicting DB entries and this has now fixed the issue.

Thank you so much for your help.

Jon

Ah, sorry about that, that first command was run on the backup DB!

After running it on the correct one I get this output:

{ "_id" : ObjectId("5a78d01c4e5630d933353da6"), "_key" : "navigation:enabled", "value" : "{"8":{"iconClass":"fa-navicon","route":"/home","title":"","text":"","textClass":"","id":"","enabled":"","properties":{}}}", "score" : 8 }

{ "_id" : ObjectId("5a78d01c4e5630d933353da5"), "_key" : "navigation:enabled", "value" : "{"7":{"iconClass":"fa-cogs","route":"/admin","title":"[[global:header.admin]]","text":"[[global:header.admin]]","textClass":"visible-xs-inline","id":"","enabled":"true","properties":{"adminOnly":true}}}", "score" : 7 }

{ "_id" : ObjectId("5a78d01c4e5630d933353da4"), "_key" : "navigation:enabled", "value" : "{"6":{"iconClass":"fa-group","route":"/groups","title":"[[global:header.groups]]","text":"[[global:header.groups]]","textClass":"visible-xs-inline","id":"","enabled":"true","properties":{"adminOnly":true}}}", "score" : 6 }

{ "_id" : ObjectId("5a78d01c4e5630d933353da3"), "_key" : "navigation:enabled", "value" : "{"5":{"iconClass":"fa-user","route":"/users","title":"[[global:header.users]]","text":"[[global:header.users]]","textClass":"visible-xs-inline","id":"","enabled":"true","properties":{"loggedIn":true}}}", "score" : 5 }

{ "_id" : ObjectId("5a78d01c4e5630d933353da2"), "_key" : "navigation:enabled", "value" : "{"4":{"iconClass":"fa-fire","route":"/popular","title":"[[global:header.popular]]","text":"[[global:header.popular]]","textClass":"visible-xs-inline","id":"","enabled":"","properties":{}}}", "score" : 4 }

{ "_id" : ObjectId("5a78d01c4e5630d933353da1"), "_key" : "navigation:enabled", "value" : "{"3":{"iconClass":"fa-tags","route":"/tags","title":"[[global:header.tags]]","text":"[[global:header.tags]]","textClass":"visible-xs-inline","id":"","enabled":"true","properties":{}}}", "score" : 3 }

{ "_id" : ObjectId("5a78d01c4e5630d933353da0"), "_key" : "navigation:enabled", "value" : "{"2":{"iconClass":"fa-clock-o","route":"/recent","title":"[[global:header.recent]]","text":"[[global:header.recent]]","textClass":"visible-xs-inline","id":"","enabled":"true","properties":{"loggedIn":true}}}", "score" : 2 }

{ "_id" : ObjectId("5a78d01c4e5630d933353d9f"), "_key" : "navigation:enabled", "value" : "{"1":{"iconClass":"fa-inbox","route":"/unread","title":"[[global:header.unread]]","text":"[[global:header.unread]]","textClass":"visible-xs-inline","id":"unread-count","enabled":"true","properties":{"loggedIn":true}}}", "score" : 1 }

{ "_id" : ObjectId("5a78d01c4e5630d933353d9e"), "_key" : "navigation:enabled", "value" : "{"0":{"iconClass":"fa-list","route":"/categories","title":"[[global:header.categories]]","text":"[[global:header.categories]]","textClass":"visible-xs-inline","id":"","enabled":"true","properties":{}}}", "score" : 0 }

{ "_id" : ObjectId("5a78ae3d4e5630d93334dcaa"), "_key" : "navigation:enabled", "value" : "{"0":{"iconClass":"fa-list","route":"/categories","title":"Forums","text":"Forums","textClass":"","id":"","enabled":"true","properties":{}}}", "score" : 0 }

So is the best solution to remove this line from the DB:

{ "_id" : ObjectId("5a78d01c4e5630d933353d9e"), "_key" : "navigation:enabled", "value" : "{"0":{"iconClass":"fa-list","route":"/categories","title":"[[global:header.categories]]","text":"[[global:header.categories]]","textClass":"visible-xs-inline","id":"","enabled":"true","properties":{}}}", "score" : 0 }

Here is the additional log output, I think I can see the issue here, is it possible I have two entries from the /categories menu both with the index of 0?

[ '{"0":{"iconClass":"fa-list","route":"/categories","title":"Forums","text":"Forums","textClass":"","id":"","enabled":"true","properties":{}}}',
'{"0":{"iconClass":"fa-list","route":"/categories","title":"[[global:header.categories]]","text":"[[global:header.categories]]","textClass":"visible-xs-inline","id":"","enabled":"true","properties":{}}}',
'{"1":{"iconClass":"fa-inbox","route":"/unread","title":"[[global:header.unread]]","text":"[[global:header.unread]]","textClass":"visible-xs-inline","id":"unread-count","enabled":"true","properties":{"loggedIn":true}}}',
'{"2":{"iconClass":"fa-clock-o","route":"/recent","title":"[[global:header.recent]]","text":"[[global:header.recent]]","textClass":"visible-xs-inline","id":"","enabled":"true","properties":{"loggedIn":true}}}',
'{"3":{"iconClass":"fa-tags","route":"/tags","title":"[[global:header.tags]]","text":"[[global:header.tags]]","textClass":"visible-xs-inline","id":"","enabled":"true","properties":{}}}',
'{"4":{"iconClass":"fa-fire","route":"/popular","title":"[[global:header.popular]]","text":"[[global:header.popular]]","textClass":"visible-xs-inline","id":"","enabled":"","properties":{}}}',
'{"5":{"iconClass":"fa-user","route":"/users","title":"[[global:header.users]]","text":"[[global:header.users]]","textClass":"visible-xs-inline","id":"","enabled":"true","properties":{"loggedIn":true}}}',
'{"6":{"iconClass":"fa-group","route":"/groups","title":"[[global:header.groups]]","text":"[[global:header.groups]]","textClass":"visible-xs-inline","id":"","enabled":"true","properties":{"adminOnly":true}}}',
'{"7":{"iconClass":"fa-cogs","route":"/admin","title":"[[global:header.admin]]","text":"[[global:header.admin]]","textClass":"visible-xs-inline","id":"","enabled":"true","properties":{"adminOnly":true}}}',
'{"8":{"iconClass":"fa-navicon","route":"/home","title":"","text":"","textClass":"","id":"","enabled":"","properties":{}}}' ]

@baris Here is the console output after adding that line:

[ { iconClass: 'fa-list',
route: '/categories',
title: 'Forums',
text: 'Forums',
textClass: '',
id: '',
enabled: 'true',
properties: {} },
undefined,
undefined,
undefined,
undefined,

db.objects.find({_key: "navigation:enabled"});

Currently mongodb. Sorry, should have mentioned that before.

Hi,

I have recently upgraded from 1.5.1 to 1.7.4, for the most part everything went well, however I seem to have lost all the menu items on the navigation bar, except for the collections icon.

I checked in the Admin area and when I try to select General > Navigation the following error occurs and the server restarts:

2018-02-15T15:50:02.456Z [31809] - error: TypeError: Cannot set property 'index' of undefined

Any idea what may be causing this?

My 1.5.1 build was a tar install so I created a new git clone of 1.5.1 and copied everything over, this looked as if it worked ok but after switching to 1.7.4 the menu has broken.

Many thanks

Jon
