In views/moove/admin/settings/plugin-boxes.php on line 110 you’re trying to output an undefined constant MOOVE_UAT_VERSION, which ends up in PHP Fatal error breaking wp-admin. For example in Cookie Banner Settings tab the WYSIWYG-editor doesn’t load. Rendering white text on white background.
Uncaught Error: Undefined constant "MOOVE_UAT_VERSION" in /app/wordpress/wp-content/plugins/gdpr-cookie-compliance/views/moove/admin/settings/plugin-boxes.php
Replacing this constant with an empty string fixes wp-admin.
