    Hi,

    When I activate the NVD3 Visualisations plugin I get the following error:

    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.

    Then if I try to put the [demosGallery] shortcode onto a page i get the following errors when i publish the page:

    Warning: Cannot modify header information - headers already sent by (output started at /home/courtosg/public_html/buddydev/wp-content/plugins/nvd3-visualisations/nvd3.php:533) in /home/courtosg/public_html/buddydev/wp-admin/post.php on line 235

    Hi,

    As usual, I would turn off all the plugins at first. There might be a conflict with some other plugin that you run.

    Turn on this plugin first and see if the error still exists.
