  • Technically that is not a bug but only a PHP deprecation warning. It still functions as it did since 7.1 (and earlier) just that PHP is warning that in future releases it could be a problem.

    If you are comfy with coding i can give you a fix to make it hush up.

    That would be great, thanks.

    Could you please share the fix? (Coding is not an issue)

    Replacing a line in “function get_replaced_urls()” seems to work:

    Replace the line
    if ( count( $this->_replaced_urls ) ) {
    with
    if ( $this->_replaced_urls && count($this->_replaced_urls) ) {
    and test.

    at least my errors seems to have been gone.
