I have these two issues:

1: WARNING: Your theme appears to be in the wrong directory for the theme name. The directory name must match the slug of the theme.

2: REQUIRED: The 

<title>

tags can only contain a call to wp_title(). Use the wp_title filter to modify the output

For #1

Based on what I searched, the text domain is the theme name both of the folder and in style.css. I have checked and they all are the same. Is it because I am using Wamp?

I have also tried inserting this to functions.php and to header.php but that resulted in the same error: load_theme_textdomain(‘themename’, get_template_directory() . ‘/languages’);

WordPress did state this but it is unclear to me that text domain is solely for WordPress.org and not for externally and locally hosted domains or is universal:

Themes that are hosted on WordPress.org the text domain must match the
slug of your theme URL (wordpress.org/themes/). This is needed so that
the translations from translate.wordpress.org work correctly.

The text domain name must use dashes and not underscores and be
lowercase. For example, if the theme’s name My Theme is defined in the
style.css or it is contained in a folder called my-theme the text
domain should be my-theme.

The text domain is used in three different places:

In the style.css theme header As an argument in the localization
functions As an argument when loading the translations using
load_theme_textdomain() or load_child_theme_textdomain() style.css
theme header #style.css theme header The text domain is added to the
style.css header so that the theme meta-data like the description can
be translated even when the theme is not enabled. The text domain
should be same as the one used when loading the text domain.

I have removed the <title> and </title> tags, yet that the error is still shown.

Please help explain, thanks.
