Functions declared in the global namespace by a theme/plugin should start with the theme/plugin prefix. Found: "add_lity_script".
Detected usage of a possibly undefined superglobal array index: $_GET['pdf']. Check that the array index exists before using it.
All output should be run through an escaping function (see the Security sections in the WordPress Developer Handbooks), found '"Content-range: bytes $first-$last/$filesize\r\n\r\n"'.
Detected usage of a non-sanitized input variable: $_GET['pdf']
$_GET['pdf'] not unslashed before sanitization. Use wp_unslash() or similar
The plugin name includes a restricted term. Your chosen plugin name - "FlowPaper" - contains the restricted term "wp" which cannot be used at all in your plugin name.
Processing form data without nonce verification.
File operations should use WP_Filesystem methods instead of direct PHP filesystem calls. Found: readfile().
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.
Mismatched text domain. Expected 'flowpaper-lite-pdf-flipbook' but got 'flowpaper'.
Direct database call without caching detected. Consider using wp_cache_get() / wp_cache_set() or wp_cache_delete().
File operations should use WP_Filesystem methods instead of direct PHP filesystem calls. Found: fclose().
File operations should use WP_Filesystem methods instead of direct PHP filesystem calls. Found: fopen().
File operations should use WP_Filesystem methods instead of direct PHP filesystem calls. Found: fread().
Plugin name "flowpaper" is different from the name declared in plugin header "FlowPaper".
PHP file should prevent direct access. Add a check like: if ( ! defined( 'ABSPATH' ) ) exit;
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.
Mismatched Stable Tag: 4.3 != 2.0.7. Your Stable Tag is meant to be the stable version of your plugin and it needs to be exactly the same with the Version in your main plugin file's header. Any mismatch can prevent users from downloading the correct plugin files from WordPress.org.
