 * Each time I update a page, the update works but I get the following warming messages:
 * “Warning: strtolower() expects parameter 1 to be string, array given in /home4/
   name/public_html/manchesterpostbasicdysphagiacourse.com/wp-includes/formatting.
   php on line 1887
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home4/name/public_html/manchesterpostbasicdysphagiacourse.com/wp-includes/
   formatting.php:1887) in /home4/name/public_html/manchesterpostbasicdysphagiacourse.
   com/wp-includes/pluggable.php on line 1179”
 * Can anyone tell me how to fix this?

 * Regarding your second warning message see [https://codex.wordpress.org/FAQ_Troubleshooting#How_do_I_solve_the_Headers_already_sent_warning_problem.3F](https://codex.wordpress.org/FAQ_Troubleshooting#How_do_I_solve_the_Headers_already_sent_warning_problem.3F)
   
   And I’d first try switching to one of the “twenty-something” standard themes 
   and trying an update. If it works then your current theme is the problem.
