Title: Error in plugin Last modified: July 24, 2020 --- # Error in plugin * Resolved [mheiselberg](https://wordpress.org/support/users/mheiselberg/) * (@mheiselberg) * [5 years, 10 months ago](https://wordpress.org/support/topic/error-in-plugin-29/) * I just upgraded the plugin and now I cannot do anything on my site. It just displays these error codes. * Warning: Use of undefined constant _FILE_ – assumed ‘_FILE_’ (this will throw an Error in a future version of PHP) in …/plugins/delete-all-comments-of-website/ delete-all-comments-of-wordpress-website.php on line 13 * Warning: Cannot modify header information – headers already sent by (output started at …/plugins/delete-all-comments-of-website/delete-all-comments-of-wordpress- website.php:13) in …/wp-includes/pluggable.php on line 1281 * I will probably just reinstall wordpress as I was redoing my site anyway, so this is just a warning to others and a heads up to the plugin creator.
