Hi
I installed GTM through your plugin with the personalized option and this code:
<?php if ( function_exists( ‘gtm4wp_the_gtm_tag’ ) ) { gtm4wp_the_gtm_tag(); } ?> just after the <body> tag on my header.php file.
Right now I´m receiving this message on my website:
Warning: Use of undefined constant ‘gtm4wp_the_gtm_tag’ – assumed ‘‘gtm4wp_the_gtm_tag’’ (this will throw an Error in a future version of PHP) in /home/customer/www/runayaq.com/public_html/wp-content/themes/oceanwp-child/header.php on line 18
Please help me, what´s the problem ?
