 * Hi,
   I’m getting these warning in the backend when the plugin is activated:
 *     ```wp-block-code

 * Hi,
 * This is a [known issue](https://wordpress.org/support/topic/warning-cannot-modify-header-information-217/)
   which will be fixed in the next plugin version (1.7.8) but the fix for this is
   already implemented in plugin’s development version:
 * [https://downloads.wordpress.org/plugin/page-scroll-to-id.zip](https://downloads.wordpress.org/plugin/page-scroll-to-id.zip)
 * If you don’t want to wait for the next version release, you can use the development
   version and update to version 1.7.8 when it becomes available (as you normally
   do).
 * Let me know if you need more help.

 * EDIT: lscache issue, it is actually working.
 * I had the latest and uploaded your dev version above (only then realising they
   were the same version – 1.7.7), no change.

   1.7.8 (which will fix this issue) will be released soon. If you want a solution
   now, please use [plugin’s development version](https://downloads.wordpress.org/plugin/page-scroll-to-id.zip).
