FIXED: PHP 8.x Error

An error occurs when using PHP 8.x:

PHP Fatal error: Uncaught TypeError: implode(): Argument #2 ($array) must be of type ?array, string given in [...]/wp-content/plugins/wp-rss-retriever/inc/lib/simplepie/library/SimplePie/Parse/Date.php:544

This error can be fixed by adjusting the file in question:
/wp-content/plugins/wp-rss-retriever/inc/lib/simplepie/library/SimplePie/Parse/Date.php

Here, lines 544 and 545 must be replaced as follows:

		$this->day_pcre = '(' . implode('|', array_keys($this->day)) . ')';
		$this->month_pcre = '(' . implode('|', array_keys($this->month)) . ')';
