# Username Field Validation Error

 * I have used the default Username field for my registration form, but it seems
   the validation is not working correctly on the default Username field.
 * I had a user who tried to register as “Narratives,” but they got an error stating
   the username had invalid characters. (“_This username is invalid because it uses
   illegal characters._ _Please enter a valid username._“) I created a username 
   for them, “narratives,” (lowercase ‘n’) with no issues.
   Can you please change
   the username field validation to allow capital letters to be submitted?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fusername-field-validation-error%2F%3Foutput_format%3Dmd&locale=en_US)

 * Hey there,
 * I’ve tested this on my WP Instance and I was able to successfully register a 
   user that has Capital letters in the Username (for example the username “Testt”).

   To investigate why you encounter this issue:​​Could you please go to your site’s
   Dashboard -> Plugins -> Installed Plugins -> and send a full screenshot with 
   everything you have installed related to Profile Builder (make sure the plugin
   version can be seen)?
 * You can use a site like [https://snipboard.io/](https://snipboard.io/) to share
   the screenshots.
 * Best regards,
