    I’m getting this error when viewing an invoice, please advice on how to resolve it.

    Warning: Cannot modify header information – headers already sent by (output started at /home/doytech/public_html/wp-includes/class.wp-styles.php:237) in /home/doytech/public_html/wp-content/plugins/sprout-invoices/controllers/_Controller.php on line 312

    If the headers are sent before the pre_si_invoice_view action hook than it would seem as though a theme or plugin modification is forcing content into the DOM inappropriately.

    Please test with some of your other plugins deactivated, or maybe your theme. Hopefully you can figure out which it is.

    You can also send me a public link to a test invoice of yours, maybe I can help.
