Hi Mattias and welcome to our :-)

Status code 500 is an internal server error so hopefully you'll find more details in the logs.

You can find the logs here Event Viewer > Windows Logs > Application.

Hope you can get some more info why you are getting the 500 error from these log files.

Thanks :)

Im not getting anything from the Event viewer..

This is the error message I got from Chrome dev toolbar:

Hi Dennis,

I see, do you have any idea of when this will be released?

What I don¨t understand is that this problem seemed to be fixed when we upgraded to version 3.0.28 and then a couple of days later the error is back.

What could possibly chagned from one day to another?

I have fixed this problem with a work-around.

I created have created a new FormsApiController and removed the Security stuff :-)

Changed the URL in /App_Plugins/Contour/formpicker.controller to backoffice/api/formsapi/getall in my case.

The api controller is still only allowed to umbraco backend users! But it will not check for read access. Which is not a problem for our editors.

Here is the source for FormsApiController

using System.Collections.Generic;
using Umbraco.Forms.Core;
using Umbraco.Forms.Data.Storage;
using Umbraco.Web.WebApi;

namespace Web.Controllers.BackendControllers
{
    public class FormsApiController : UmbracoAuthorizedApiController
    {
        public IEnumerable<Umbraco.Forms.Core.Providers.V7.Models.Form> GetAll()
        {
            List<Umbraco.Forms.Core.Providers.V7.Models.Form> list = new List<Umbraco.Forms.Core.Providers.V7.Models.Form>();
            FormStorage formStorage = new FormStorage();
            foreach (Form f in formStorage.GetAllForms(false))
            {
                // Bypass the Security
                //if (Security.HasAccessToForm(f.Id))
                //{
                list.Add(new Umbraco.Forms.Core.Providers.V7.Models.Form()
                    {
                        Id = f.Id,
                        Name = f.Name,
                        Fields = this.GetFormFields(f)
                    });
                //}
            }
            formStorage.Dispose();
            return list;
        }

        private string GetFormFields(Form f)
        {
            string[] strArray = new string[] { "one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten" };
            string str1 = string.Empty;
            if (f.AllFields.Count <= 4)
            {
                int num = 1;
                foreach (Field field in f.AllFields)
                {
                    str1 += field.Caption;
                    if (num == f.AllFields.Count - 1)
                        str1 += " and ";
                    else if (num < f.AllFields.Count)
                        str1 += " ,";
                    ++num;
                }
            }
            else
            {
                for (int index = 0; index < 3; ++index)
                    str1 = str1 + f.AllFields[index].Caption + " ,";
                string str2 = str1 + f.AllFields[3].Caption + " and ";
                if (f.AllFields.Count > 14)
                {
                    str1 = str2 + " and a lot more";
                }
                else
                {
                    str1 = str2 + strArray[f.AllFields.Count - 5] + " additional field";
                    if (f.AllFields.Count != 1)
                        str1 += "s";
                }
            }
            return str1;
        }
    }

@Christian Palm No need to "Bypass the Security". You just need to specify namespace of 'Security' class. (Since Umbraco 7.3 - 'Security' is a new property to 'UmbracoApiControllerBase' class of type 'Umbraco.Web.Security.WebSecurity')

-- All you need to do is:

Declare alias to Umbraco.Forms.UI

using ui = Umbraco.Forms.UI;

Use new namespace alias

if (ui.Security.HasAccessToForm(f.Id))

Note: You can't use directly 'Umbraco.Forms.UI.Security.HasAccessToForm(f.Id)' because 'Umbraco' in this scope reffers to property on 'Umbraco.Web.WebApi.UmbracoApiControllerBase' of type 'Umbraco.Web.UmbracoHelper'
