 * Hello,
 * This is a [known issue](https://wordpress.org/support/topic/warning-cannot-modify-header-information-217/)(
   [see my reply here](https://wordpress.org/support/topic/warning-cannot-modify-header-information-217/#post-16335138)).
   You just need to download the development version from the link below and use
   it replacing the current plugin version you have:
 * [https://downloads.wordpress.org/plugin/page-scroll-to-id.zip](https://downloads.wordpress.org/plugin/page-scroll-to-id.zip)
 * You can keep using the [development version](https://downloads.wordpress.org/plugin/page-scroll-to-id.zip)
   and update to version 1.7.8 when it becomes available, as you normally do.
 * Let me know if you need more help.
