I just installed the latest Umbraco version (7.10.1) on a blank SQL database.
Since my project requires role based protection I created a few members and was about to create the appropriate member groups.
However, when I click the three dots on Member Groups folder and select Create I get the following YSOD:
Server Error in '/' Application.
Value cannot be null.
Parameter name: type

Did anyone else had this problem? Or even better, does someone know how to fix this?
Thanks for any help
there is an issue created here with a PR already: http://issues.umbraco.org/issue/U4-11155
You can vote it up.
Hope this helps!
I up-voted the issue. Hopefully the fix will be available soon :-)
it will be in version 7.9.4 and 7.10.2 but no release date available for the moment.
Have a nice day.
If i'm correct they will be released tomorrow.
Thanks for the info Dave!
Hope it's released soon, this is a huge issue for me and my client
I get the same error in Umbraco version (7.10.1).
I created member groups programmatically using the following method.
static void CreateMemberGroup(string name)
Umbraco.Core.Services.IMemberGroupService mgs = ApplicationContext.Current.Services.MemberGroupService;
if (mgs.GetByName(name) != null)
MemberGroup group = new MemberGroup()
Name = name
You can also simply create a group with:
var memberService = ApplicationContext.Current.Services.MemberService;
And delete it with:
var memberGroupService = ApplicationContext.Current.Services.MemberGroupService;
var group = memberGroupService.GetByName("Group Name");
I just downloaded version 7.10.2 and I can confirm the issue has been resolved.
thanks for reporting it back to the community! #h5yr
Have a nice day!
Just upgraded one of ours to 7.9.4 and can confirm it's fixed on this version also.
I'm getting this error now on 7.9.6 - Previously I was on 7.9.4 and it was working without issue.
Looking at the CMS source in github, looks like a fix was merged into branch 7.9.4 but was not included into 7.9.5 - So that's why it's also not in 7.9.6.... the >7.10.2 branch seems fine, so may i'll just try upgrade to that.
Probably you need to create a issue than at http://issues.umbraco.org
Is strange it's not included anymore.
Actually found another issue that had been fixed but was missing from 7.9.5 and 7.9.6,
logged it: http://issues.umbraco.org/issue/U4-11346
is working on a reply...
