So the problem is if you have empty values for settings as “Redirect URL for inactive keys”, etc. then you will get above error message. When you set a value there (all 3 input fields), it will output this error:`Warning: Undefined array key 0 in /home/httpd/vhosts/_/httpdocs/wordpress/ wp-content/plugins/dynamic-qr-code/sos/wp/data/field.php on line 400 Warning: Cannot modify header information - headers already sent by (output started at/ home/httpd/vhosts/_/httpdocs/wordpress/wp-content/plugins/dynamic-qr-code/sos/ wp/data/field.php:400) in /home/httpd/vhosts/_/httpdocs/wordpress/wp-includes/ pluggable.php on line 1435 Warning: Cannot modify header information - headers already sent by (output started at /home/httpd/vhosts/_/httpdocs/wordpress/wp- content/plugins/dynamic-qr-code/sos/wp/data/field.php:400) in /home/httpd/vhosts/_/ httpdocs/wordpress/wp-includes/pluggable.php on line 1438` * Which led me to the solution above.

Also the post structure given by custom taxonomy enables better usability in the backend and in the frontent a consistent permalink structure. * Yes, I had a look at Template Hierarchy, and also the naming seems correct, since the template got recognized. But the assignment of custom page with the template did not work out well. Maybe I have to read more about the query. Basically, it would be enough to show the WYSIWYG-content. Any help on how the query has to be? (I tried to copy page template content but it did not work). * Thanks * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[MC4WP: Mailchimp for WordPress] ERROR: Contact Form 7 > Mailchimp API Error: Not Found.
