Processing form data without nonce verification.

$_REQUEST['rtoc_back_button_color'] not unslashed before sanitization. Use wp_unslash() or similar

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

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

error_log() found. Debug code should not normally be used in production.

debug_backtrace() found. Debug code should not normally be used in production.

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

Detected usage of a non-sanitized input variable: $_SERVER['HTTP_HOST']

Detected usage of a possibly undefined superglobal array index: $_SERVER['HTTP_HOST']. Check that the array index exists before using it.

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.

Use of heredoc syntax (<<<) is not allowed; use standard strings or inline HTML instead

Functions declared in the global namespace by a theme/plugin should start with the theme/plugin prefix. Found: &quot;book_stealth_load_textdomain&quot;.

wp_redirect() found. Using wp_safe_redirect(), along with the &quot;allowed_redirect_hosts&quot; filter if needed, can help avoid any chances of malicious redirects within code. It is also important to remember to call exit() after a redirect so that no other unwanted code is executed.

In footer ($in_footer) is not set explicitly wp_enqueue_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.

Tested up to: 6.8 < 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.

One or more tags were ignored. Please limit your plugin to 5 tags.

The "Short Description" section is too long and was truncated. A maximum of 150 characters is supported.
