Hi can someone explain to me part 2 of this fix?
and replace the line just after :
$url_featured_image = ( ! empty ( wp_get_attachment_url( get_post_thumbnail_id( get_the_ID() ) ) ) ? wp_get_attachment_url( get_post_thumbnail_id( get_the_ID() ) ) : null );by
$url_featured_image = ( ! empty ( $attachment_url ) ? wp_get_attachment_url( get_post_thumbnail_id( get_the_ID() ) ) : null );I’m confused, the next line is empty space, after the empty space I have
if ( ! empty( $url_featured_image ) ) { return $url_featured_image;so what the heck do I replace?
or can someone send me the modified file.
My whole site now is down because of this plugin and I tried pasting replacing lines and things and still having this issueThis is my complete file “wp-content/plugins/all-in-one-event-calendar/app/view/event/content.php” after I made the changes.
