Troubleshooting Invoice/Estimate Templates

Header Content Injection

Some plugins and themes inject content around all WordPress templates regardless of content, and while I could rant about how this technique is terrible in every instance I'm going to hopefully provide a way to solve it for you.

First, here is an example of what it may look like. In this example a navigation is inserted before the the Sprout Invoices estimate template, which would cause a "headers already sent" in some instances.

Solutions:

• Determine the plugin causing the issue. 
  • The plugin may have an option to disable the template injection based on post types (i.e. sa_invoice, and sa_estimate).
  • Contact the plugin author about not having an option, maybe they have a filter to help.
• Determine the theme causing the issue.
  • The theme may have an option to disable the template injection based on post types (i.e. sa_invoice, and sa_estimate).
  • Contact the theme author about not having an option, maybe they have a filter to help.

Make sure to contact support, so that we know which plugin or theme is having the incompatibility. We may have a quick filter/action/solution for you so you don't have to wait for the developer.

Known Themes

Bellevue Theme

This theme uses a Roots_Wrapping class to wrap all WP templates. There are filters included but many do not work. The quick solution is to copy the invoice and estimate templates to your theme.

1. Copy /views/templates/invoice/invoice.php and /views/templates/estimate/estimate.php to the theme directory.
2. Rename them to base-invoice.php and base-estimate.php respectively.
