I am getting this error message when I ma trying to open Advanced settings ( attached JPG). Can You look at it, what caused a problem ? Many thanks.
Try to check your SiteMap - there can be something wrong with links or entities. When you fix it - the error will disappear
Hello Eliz, thank You for help.It was something wrong with SiteMap, but I could not solve it without MS Supports. They suggested me to delete some layers and after that it was ok. However - many thanks.
