I've installed Custom Press on a virtually fresh Wordpress MS site. The only other plugins on the site are WPMU DEV and Akismet. After selecting all of the options I want for my custom post type, when I click on "Add post type", I get this error at the top of the screen:
Notice: Undefined index: cf_columns in /home/qultshow/public_html/wp-content/plugins/custompress/core/content-types.php on line 234
Warning: Cannot modify header information - headers already sent by (output started at /home/qultshow/public_html/wp-content/plugins/custompress/core/content-types.php:234) in /home/qultshow/public_html/wp-includes/pluggable.php on line 876
The custom post type is created, but whenever I edit it, the same error is shown at the top of the page. Why does this error show up?
