Hi, whenever we post or update a post anything, we get a white screen with the following error:
Notice: Undefined index: custom_feeds in ~path/wp-content/plugins/powerpress/powerpressadmin.php on line 2484
Warning: Cannot modify header information - headers already sent by (output started at ~path/wp-content/plugins/powerpress/powerpressadmin.php:2484) in ~path/wp-includes/pluggable.php on line 876
How can I fix this error?
- happens regardless of post type
- happens whether we actually use the plugin meta box or not
- happens regardless of theme
- only started happening when we integrated our blubrry hosting account
