If I add the function:
add_theme_support( ‘title-tag’ );

combined with:
acf_add_options_page(my settings…);

Then I get wp_debug notice:
Notice
: Array to string conversion in
/Users/imac/Sites/ak/wp-includes/general-template.php
on line
1005

I am not the only one who found this,

I use WP 4.5.1 and latest ACF5 pro.

Hi guys

Thanks for the tag.
It sounds like using the variable $page is causing issues. Please note this can’t be replicated 100% of the time, so there must be something else to this story which is causing some function.php files to modify a global var instead of a local one.

A simple fix is to place your ACF code within an action or function to avoid namespace issues!
