@ngdoc error @name $interpolate:nochgmustache @fullName Redefinition of start/endSymbol incompatible with MessageFormat extensions @description You have redefined `$interpolate.startSymbol`/`$interpolate.endSymbol` and also loaded the `ngMessageFormat` module (provided by angular-message-format.min.js) while creating your injector. `ngMessageFormat` currently does not support redefinition of the startSymbol/endSymbol used by `$interpolate`. If this is affecting you, please file an issue and mention @chirayuk on it. This is intended to be fixed in a future commit and the github issue will help gauge urgency. For more information about the MessageFormat syntax in interpolation expressions, please refer to MessageFormat extensions section at {@link guide/i18n#MessageFormat AngularJS i18n MessageFormat}
