Hi,

I added a new Tab to the membership type called "Membership Photo". There, I added a new property called "Avatar" and selected "Image Cropper" as the editor. Also, I configured the cropper by adding 1 crop size. All is well till here.

I go back to an already created member, upload an image and then hit save, I get the following error:

Server error: Contact administrator, see log for full details. The given key was not present in the dictionary.

That's the log here:

2016-08-26 09:46:40,344 [P11964/D4/T126] WARN Umbraco.Core.Models.Member - Trying to access the 'PasswordQuestion' property on Umbraco.Core.Models.Member but the umbracoMemberPasswordRetrievalQuestion property does not exist on the member type so a default value is returned. Ensure that you have a property type with alias: umbracoMemberPasswordRetrievalQuestion configured on your member type in order to use the 'PasswordQuestion' property on the model correctly.

Ensure that you have a property type with alias: umbracoMemberPasswordRetrievalQuestion configured on your member type in order to use the 'PasswordQuestion' property on the model correctly.

Please note that the above occurs only for existing members. The Member Type was edited after creating the member. For new members, all works well.

I tried to add additional properties on the Member Type. Same problem. All existing members won't be able to save and I get the above error. New properties apply successfully to new members only.

Any idea?

Thanks
