The warnings you’re seeing are due to the fact that the variable $item is not defined properly before it is accessed in the validate_dirlist method of your plugin. Specifically, the code is trying to access the array offset on a variable that may not have been initialized.

The issue lies in this part of the code in the validate_dirlist method (around line 211):

if ( $item['type'] === 'f' && strpos( $item, "." ) !== false ) {
    return true;
}

The variable $item is being used without being initialized first. To resolve this, you’ll need to iterate through the $list array properly and ensure that $item is defined before trying to access its properties.

Here’s the corrected version of your validate_dirlist function:

private function validate_dirlist( $list ) {

    foreach ( $list as $item ) {

        // Ensure $item is defined and is an array
        if ( ! isset( $item['type'] ) || ! is_array( $item ) ) {
            continue; // Skip invalid or undefined items
        }

        // check if it's a file and contains a dot (.)
        if ( $item['type'] === 'f' && strpos( $item['name'], "." ) !== false ) {
            return true;
        }

        // validate subdirectories recursively
        if ( $item['type'] === 'd' && ! empty( $item['files'] ) && is_array( $item['files'] ) ) {
            if ( ! $this->validate_dirlist( $item['files'] ) ) {
                return false;
            }
        }

    }

    return true;
}

Im also having this issue, administrator user can post links, etc… subscribers can’t, it was working fine a few days ago…

I had the same issue, fixed by adding the following code to the functions.php file

function _bd_force_https()
{
    if ( empty( $_SERVER['HTTPS'] ) ) return;
    ob_start();
}
add_action( 'template_redirect', '_bd_force_https', 1 );

function _bd_output_https_page()
{
    if ( empty( $_SERVER['HTTPS'] ) ) return;
    echo str_ireplace( 'http://', 'https://', ob_get_clean() );
}
add_action( 'wp_footer', '_bd_output_https_page', 99 );
