After renaming the files of my templates and inside the file with php, it is looking for the old templates. The dropdown is no longer available. Why is this happening and how to fix that?

The only files i modified is the template-parts folder inside the child theme. I did not touch the class-wp-theme.php where it is the warning.

    this is a known bug within WordPress 4.9 where WordPress saves the template file name and doesn't gracefully fail when the template is no longer there

  • To speed up this process you can change your theme's version because its cached with the theme version. Later you can just change it back

If you have WP-CLI installed, try to run wp cache flush


you can put this code into your functions.php

function fix_template_caching( WP_Screen $current_screen ) {
    if ( ! in_array( $current_screen->base, array( 'post', 'edit', 'theme-editor' ), true ) ) {
    $theme = wp_get_theme();
    if ( ! $theme ) {
    $cache_hash    = md5( $theme->get_theme_root() . '/' . $theme->get_stylesheet() );
    $label         = sanitize_key( 'files_' . $cache_hash . '-' . $theme->get( 'Version' ) );
    $transient_key = substr( $label, 0, 29 ) . md5( $label );
    delete_transient( $transient_key );

add_action( 'current_screen', 'fix_template_caching' );
