The WP-Andreas01 theme has not been updated for 10 years and is becoming increasingly incompatible with our version of WordPress.
We have decided to retire the theme. This means it will be no longer available to select in the Themes section of your dashboard or through the customizer.
If your blog currently uses WP-Andreas01 it will continue to do so unless you change to another theme. You will then not be able to switch back.
We would suggest that switching to another theme to take advantage of the many changes and improvements in WordPress over the last 10 years.
