 * This plugin is causing an error when editing pages and posts. The page will resolve,
   however, the error message is consistent during page load:
 * Cannot modify header information – headers already sent by (output started at/
   home/customer/www/example.com/public_html/wp-content/plugins/custom-fonts/classes/
   class-bsf-custom-fonts-render.php:292)
 * If it’s helpful, the rest of the error is:
 *  in /home/customer/www/example.com/public_html/wp-admin/admin-header.php on line
   9
 * This is happening on all of my client sites that are using your plugin. It started
   after an update about a month or so ago.
 * Can you please let me know if this is a known bug and if there is a fix coming
   soon. Or, if not, when you will have a fix for this?

 * Hi [@juleshenson](https://wordpress.org/support/users/juleshenson/),
 * Since we are not able to replicate this, is there any specific step to replicate
   this? Could you please share with us?
 * Or please reach out to us through our [Support Portal](https://wpastra.com/contact/),
   so we can take a look at this closer?
 * Kind regards,
    Herman 😊

 * Hi [@bsfherman](https://wordpress.org/support/users/bsfherman/) I have Astra 
   installed on one of the sites it is happening with, so you can try to recreate
   with Astra theme. To replicate, you just have go to WP admin, then click to edit
   a post or a page. The error message pops up at the top of the screen before the
   edit page loads.
 * I will also submit a ticket on the support portal.
