I tried to upgrade my PHP version from 7.0 to 7.4, I followed all the instructiones, made the backup, deactivated all the plugins… Still there is a fatal error…
Fatal error: Uncaught Error: Call to undefined function wp_register_tinymce_scripts() in /web/htdocs3/skolaprachencz/home/www/wp-includes/script-loader.php:633 Stack trace: #0 /web/htdocs3/skolaprachencz/home/www/wp-includes/class-wp-hook.php(310): wp_default_packages(Object(WP_Scripts)) #1 /web/htdocs3/skolaprachencz/home/www/wp-includes/class-wp-hook.php(334): WP_Hook->apply_filters(NULL, Array) #2 /web/htdocs3/skolaprachencz/home/www/wp-includes/plugin.php(565): WP_Hook->do_action(Array) #3 /web/htdocs3/skolaprachencz/home/www/wp-includes/class-wp-scripts.php(185): do_action_ref_array(‘wp_default_scri…’, Array) #4 /web/htdocs3/skolaprachencz/home/www/wp-includes/class-wp-scripts.php(160): WP_Scripts->init() #5 /web/htdocs3/skolaprachencz/home/www/wp-includes/functions.wp-scripts.php(24): WP_Scripts->__construct() #6 /web/htdocs3/skolaprachencz/home/www/wp-includes/functions.wp-scripts.php(187): wp_scripts() #7 /web/htdocs3/skolaprachencz/home/www/wp-includes/blocks.php(173): wp_register_script(‘wp-block-file-v…’, ‘ in /web/htdocs3/skolaprachencz/home/www/wp-includes/script-loader.php on line 633
