Anyone had this before?

Jeroen

Hi Jeroen,

I have the same issue, for me it occurs when i login to the site, so probably something is happening with the authentication.

Anyone has an solution to this problem?

Gr. Robin.

The moment a cookie is set it goes wrong. In your case when a member does a login.

Jeroen

Any luck fixing it yet?

Nope sorry I just made sure no cookie was set.

I am the same issue.

I think that the issue fires when I take 2 pages opened in same browser. One in frontend and one in backoffice.
The issue fires 75% of times that I try to save a content or go to another content.

How can I solve it?

hi Jeroen - did you ever find out what was causing this and if there is a known fix? We're seeing this sporadically on a 7.2.5 site. thanks

Hi Andrew,

I found a correlation with Frontend login.
Look this: https://our.umbraco.org/forum/umbraco-7/using-umbraco-7/65380-Backend-go-crash-when-navigating-Frontend-in-same-browser

I found the solution in my code.

The issue was fired when javascript call a API Controller. This API had SetAngularAntiForgeryTokens attribute that reset XSRF cookie.
Look here: http://issues.umbraco.org/issue/U4-4149

I removed the attribute from method, then backoffice works properly.

I'm having a similar issue. I've only been able to fix it by resetting the site on the server. Also only happens on FireFox. Chrome eventually loads the links and dashboard, but it is notably slower than normal.

I posted another topic here: https://our.umbraco.org/forum/umbraco-7/using-umbraco-7/71950-bug-empty-dashboard-firefox

This is a serious problem for my users.

I had the same issue. I cleared my cookies and now it works fine.

I had to clear my browser (chrome) cache using the tools availble to do so.

i am having the same issue on several solutions... a proper fix to this would be greatly appreciated...

Hello All,

I am facing the same issue with Umbraco version 7.1.4 assembly: 1.0.5261.28127

Not able to find the below files in umbraco folder :

umbraco/backoffice/UmbracoApi/UpdateCheck/GetCheck Failed to load resource: the server responded with a status of 417 (Missing token)

umbraco/backoffice/UmbracoApi/Section/GetSections Failed to load resource: the server responded with a status of 417 (Missing token)

Also I don't have backoffice folder in the installed umbraco site folder.

Help me its urgent.

Thanks in advance. Pradip

Yes, It's not working.

Hello,

I've got the same issue. After pressing F5 to refresh the page, the Back-End works. But this solution can't be the fix for this. Does anyone found a better solution?

Umbraco 7.2.8 -- Server 2012 sp1

removing KB4014604 fixed the issue for us

Hi Daniel,

thank you for your answer. KB4014604 isn't even installed on my computer. :(

Some of the other comments (related threads) have mentioned the 4.7 framework (which we didn't have on our server) which I am sure includes some of the same fixes for .net that were in that KB4014604.

So if you have framework 4.7 installed on your computer that may be it.

I have also read that upgrading past 7.3 fixes it (we're on 7.2.8) I will give that a shot later in the day to see if it works and report back.

Hi guys,

I fixed it finally! I have severall Umbraco Projects with diffrent versions. 7.2.4 - Login Bug 7.2.1 - Login Bug 7.2.1 - Login Bug 7.3.0 - No Bug 7.4.3 - No Bug

So i decided to Upgrade the 7.2.x Projects to 7.3.0 and the bug was fixed.

I hope i could help some of you with this result.

I did this in visual studio 2015 via Nuget packet Manager with the following command.

Update-Package UmbracoCms -Version 7.3.0

Your Welcome

David

Hi,

For me the problem was that some pickers that were updated to the new ones still stored the ID in the index, did not matter if we rebuild it or restarted the site. The problem is that Umbraco shows nothing selected in the pickers though they have data stores behind it, to fix it you need to selected some node with the picker, remove it and save again.

This will completely remove it from the database.

Hope this helps someone.

Hi everyone,

I have had the same issue on a 7.12.4 site.

Sometime it has been fixed by removing all items in the obj folder, clear the APP_DATA cache, clearning cookies, rebooting the webserver bla bla bla.

Last time I got this issue (today), none of the above worked.

In order to make it work this time, I had to do the following steps:

1. Change umbracoUseSSL = true in web.config.
2. Change the visual studio to use SSL

Though I agree, this is a horrible bug that really drains hours of the productivity of this otherwise great product.

Best regards

To be clear, the above is related to development in Visual Studio.. not live on a production site - thankfully for me.

Everytime this happens, I completely delete umbraco, restart visual studio, and then install umbraco again.

Deleting umbraco includes deleting umbraco, and umbraco_client, obj and bin folders. And the every thing inside app data folder.

If it helps, I've only had this issue when the front end loads some cookie preference javascript (e.g. https://www.civicuk.com/cookie-control or https://www.cookiebot.com/en/) which then deletes the UMB-XSRF-TOKEN.

In most cases the issue was still occurring even when the backoffice was the only tab open. In this scenario, I checked the browser's dev tools Network view and I could see that a backoffice resource was 404ing and so was in turn loading a front end page and loading the page's cookie preference javascript.

Fix the 404(s) and it resolves the issue.

Hope this helps someone.

I just had this issue after upgradeing to 7.6.14

I could solve it by changing clientdependency version to something higher.

~/config/clientDependency.config

<clientDependency version="(Change to something higher)" fileDependencyExtensions=".js,.css" loggerType="Umbraco.Web.UI.CdfLogger, umbraco">

Old thread but I was still getting this. The cause was that some of the login cookies were being ignore. Edge's WebDev tools were showing a warning in the login response that existing HTTPS cookie would supersede these cookies and so they would be ignored.

I was logging in via http://localhost, and clearing the cookies via WebDev tools appeared to leave some previously set at https://localhost in place. Once I deleted these https cookies I was all good.

I'm not sure how these cookies were set in the first place, but my guess is another project is set to use the backoffice via SSL.

is working on a reply...
