The error indicates that the function is declared twice. Please check your code, locate the duplicate declaration, and remove it.

I recently got this after updating to the latest wpforo. I have a wpcode snippet that does this:

function my_custom_email_html_tags( $allowed_html ){
if( $allowed_post_html = wp_kses_allowed_html( 'post' ) ){
$allowed_html = $allowed_post_html;
}
return $allowed_html;
}
add_filter( 'wpforo_kses_allowed_html_email', 'my_custom_email_html_tags');

So it allows for custom css/html I believe. Did something change in the recent release that caused this behaviour?

 

Thank you for any tips!
