Mismatched text domain. Expected 'advanced-custom-fields' but got 'acf'.
Functions declared in the global namespace by a theme/plugin should start with the theme/plugin prefix. Found: "_acf_apply_deprecated_hook".
Hook names invoked by a theme/plugin should start with the theme/plugin prefix. Found: "'acf/schema/post_field_objects/post_type=' . $post_type".
Global variables defined by a theme/plugin should start with the theme/plugin prefix. Found: "$acf".
Classes declared by a theme/plugin should start with the theme/plugin prefix. Found: "ACF".
PHP file should prevent direct access. Add a check like: if ( ! defined( 'ABSPATH' ) ) exit;
All output should be run through an escaping function (see the Security sections in the WordPress Developer Handbooks), found 'acf_esc_attrs'.
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.
$_GET[$key] not unslashed before sanitization. Use wp_unslash() or similar
Namespaces declared by a theme/plugin should start with the theme/plugin prefix. Found: "ACF\AI".
Processing form data without nonce verification.
Detected usage of a non-sanitized input variable: $_FILES['acf']
Missing singular placeholder, needed for some languages. See https://codex.wordpress.org/I18n_for_WordPress_Developers#Plurals
Direct database call without caching detected. Consider using wp_cache_get() / wp_cache_set() or wp_cache_delete().
In footer ($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.
Detected usage of tax_query, possible slow query.
Hook names invoked by a theme/plugin should start with the theme/plugin prefix. Found: "$filter/$variation=$value".
The "acf/field" prefix is not a valid namespace/function/class/variable/constant prefix in PHP.
Function "register_block_bindings_source()" requires WordPress 6.5.0, but your plugin minimum supported version is WordPress 6.2.0.
date() is affected by runtime timezone changes which can cause date/time to be incorrectly displayed. Use gmdate() instead.
The $text parameter must be a single text string literal. Found: $string
Using exclusionary parameters, like exclude, in calls to get_posts() should be done with caution, see https://wpvip.com/documentation/performance-improvements-by-removing-usage-of-post__not_in/ for more information.
Setting `suppress_filters` to `true` is prohibited.
The use of function set_time_limit() is discouraged
