Hello! We are trying to update an old client website based on X. After I have updated to the latest WP, Plugins and Theme I have now errors on the frontend:
Warning: preg_match() expects parameter 2 to be string, array given in /kunden/483828_80538/webseiten/webhomes.de/rochelt/wp-includes/class.wp-styles.php on line 340
Warning: strpos() expects parameter 1 to be string, array given in /kunden/483828_80538/webseiten/webhomes.de/rochelt/wp-includes/class.wp-styles.php on line 340
Can you please help me?
I also can not find a way to update the cornerstone plugin. Can you guide me to it’s download location please?
Thank you!
