Colorlib 404 Customizer

PHP file should prevent direct access. Add a check like: if ( ! defined( 'ABSPATH' ) ) exit;

All output should be run through an escaping function (like esc_html_e() or esc_attr_e()), found '_e'.

All output should be run through an escaping function (see the Security sections in the WordPress Developer Handbooks), found '$ajax_nonce'.

Resource version not set in call to wp_enqueue_style(). This means new versions of the style may not always be loaded due to browser caching.

Processing form data without nonce verification.

Global variables defined by a theme/plugin should start with the theme/plugin prefix. Found: "$cl".

load_plugin_textdomain() has been discouraged since WordPress version 4.6. When your plugin is hosted on WordPress.org, you no longer need to manually include this function call for translations under your plugin slug. WordPress will automatically load the translations for you as needed.

date() is affected by runtime timezone changes which can cause date/time to be incorrectly displayed. Use gmdate() instead.

Version parameter is not explicitly set or has been set to an equivalent of "false" for wp_register_script; This means that the WordPress core version will be used which is not recommended for plugin or theme development.

In footer ($in_footer) is not set explicitly wp_register_script; It is recommended to load scripts in the footer. Please set this value to `true` to load it in the footer, or explicitly `false` if it should be loaded in the header.

A function call to __() with texts containing placeholders was found, but was not accompanied by a "translators:" comment on the line above to clarify the meaning of the placeholders.

Mismatched "Tested up to": 6.9 != 6.8. The "Tested up to" value in the readme file must match the "Tested up to" value in the plugin header. If the plugin header has a "Tested up to" value, it will override the readme value, which can cause confusion.

Tested up to: 6.9 < 7.0. The "Tested up to" value in your plugin is not set to the current version of WordPress. This means your plugin will not show up in searches, as we require plugins to be compatible and documented as tested up to the most recent version of WordPress.

The "Short Description" section is missing. An excerpt was generated from your main plugin description.

Function "wp_enqueue_editor()" requires WordPress 4.8.0, but your plugin minimum supported version is WordPress 4.7.0.
