Front Page Box Widgets Disappeared After Theme Upgrade

I have the same problem: I get the following error:

Fatal error: Call to undefined function optimizer_attachment_id_by_url() in /web/htdocs/www.rosaliagreco.com/home/wp-content/themes/optimizer/framework/core-functions.php on line 194

I experience the same problem after today’s update. Plus on the frontpage I also lost the editing part that is normally displayed at the top. Hopefully someone can help.

Looks like a bug. Can you please go to Appearance >Editor and select core-functions.php and add this to the very bottom of the file:

//**Return an ID of an attachment by searching the database with the file URL (Inexpensive query)**//
function optimizer_attachment_id_by_url( $url ) {
	$parsed_url  = explode( parse_url( WP_CONTENT_URL, PHP_URL_PATH ), $url );

	$this_host = str_ireplace( 'www.', '', parse_url( home_url(), PHP_URL_HOST ) );
	$file_host = str_ireplace( 'www.', '', parse_url( $url, PHP_URL_HOST ) );

	if ( ! isset( $parsed_url[1] ) || empty( $parsed_url[1] ) || ( $this_host != $file_host ) ) {
		return;
	}

	global $wpdb;
	$attachment = $wpdb->get_col( $wpdb->prepare( "SELECT ID FROM {$wpdb->prefix}posts WHERE guid RLIKE %s;", $parsed_url[1] ) );
	return $attachment[0];
}

We will fix this pretty soon. Thanks for your patience.

Success!!

Great, it worked! Thanks for the quick reply

HELP! i pasted that and now i cannot open my website or even the wordpress admin panel it gives me this error:

Fatal error: Cannot redeclare optimizer_attachment_id_by_url() (previously declared in /home/sslsghfz/public_html/cyboard.xyz/wp-content/themes/optimizer_pro/framework/core-functions.php:366) in /home/sslsghfz/public_html/cyboard.xyz/wp-content/themes/optimizer_pro/framework/core-functions.php on line 436

@amrrr Sounds like the update did not go well. Can you please switch to another theme and delete Optimizer from Appearance > Themes and then install the theme again? Your theme settings should be intact, so dont worry about that.

Thanks
