An SEOPress error occurred when upgrading PHP 8.1 (ea-php81). On the XML-HTML Sitemap page, when you press Ping Google manually or auto to send the Sitemap, the error will appear as follows:
[23-Mar-2023 07:52:45 UTC] PHP Warning: foreach() argument must be of type array|object, null given in /home/********/public_html/********/wp-content/plugins/wp-seopress/inc/functions/sitemap/template-xml-sitemaps.php on line 215I dropped back to PHP 7.4, almost no error messages, I don’t know what’s wrong?
Many Thanks
