The plugin no longer works…error msg: Cannot modify header information – heade

  • Hi,

    I’ve created numerous duplicated pages with the plugin a few months ago and it worked well, however, I tried to do it again as I normally did in the past, but now got the following error messages:

    The plugin generated 2 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.

    Warning: Cannot modify header information – headers already sent by (output started at /home/demo12m/public_html/wp-content/plugins/duplicate-wp-page-post/duplicate-wp-page-post.php:1) in /home/demo12m/public_html/wp-admin/post.php on line 197

    Warning: Cannot modify header information – headers already sent by (output started at /home/demo12m/public_html/wp-content/plugins/duplicate-wp-page-post/duplicate-wp-page-post.php:1) in /home/demo12m/public_html/wp-includes/pluggable.php on line 1210

    Any ideas what’s going on? Thanks.
