same on the forgotten password page and forgotten username page

I can partly solve this by using in validate.js

          } else {
            message = Joomla.JText._('JLIB_FORM_CONTAINS_INVALID_FIELDS');
          }

          error = {
            [Joomla.JText._('ERROR')]: [message] // INSTEAD of error:[message]
          };
          Joomla.renderMessages(error);
        }

and adding
Text::script('ERROR');
in FormvalidateAssetItem.php method public function onAttachCallback(Document $doc)

	public function onAttachCallback(Document $doc)
	{
		// Add validate.js language strings
		Text::script('JLIB_FORM_CONTAINS_INVALID_FIELDS');
		Text::script('JLIB_FORM_FIELD_REQUIRED_VALUE');
		Text::script('JLIB_FORM_FIELD_REQUIRED_CHECK');
		Text::script('JLIB_FORM_FIELD_INVALID_VALUE');
		Text::script('ERROR');
	}

But I get the info blue color which is the default...

This issue may not only exists for this specific error, but for all js trigered errors as far as I could see.

@infograf768 its easier than that

Just add the following to the registration form etc

// Load JavaScript message titles
Text::script('ERROR');
Text::script('WARNING');
Text::script('NOTICE');
Text::script('MESSAGE');

You are correct. Now remains to find out where it also has to be added.
Why not add these in the template index.php so to not bother anymore. That is what we do for installation.

will do patch in index.php

Closing as we have a patch
