Hello kuba
Thank you for your reaction! It would be an IP address, but, in the meantime I figured out is isn’t Wordfence that is causing the problem but the theme that the website uses. Because everything works fine when I switch to the default Twenty Twenty-three theme.
So my question has changed. I didn’t find the wp_body_open() function in the theme. I tried to add the following snippet:
if ( ! function_exists( 'wp_body_open' ) ) {
function wp_body_open() {
do_action( 'wp_body_open' );
}
}
with the ‘Snippets’ plugin. But that doesn’t work. Any suggestions what I can do next?
(Maybe I’d better close this topic and start a new one?)
Kind regards
Karin
