Title: problem with related posts Last modified: August 24, 2016 --- # problem with related posts * Resolved [moray](https://wordpress.org/support/users/moray/) * (@moray) * [11 years, 1 month ago](https://wordpress.org/support/topic/problem-with-related-posts-3/) * hi there. I had Jetpack working perfectly on old website. The theme depreciated so i switched to a genesis framework to be safe into the future. However the related posts module isnt working properly. I uninstalled it and deleted everything via FTP. I then re-installed and got this error: * Warning: Cannot modify header information – headers already sent by (output started at /home/mutantsp/public_html/wp-content/plugins/jetpack/modules/related-posts/ jetpack-related-posts.php:1) in /home/mutantsp/public_html/wp-includes/option. php on line 749 * I love the module and would appreciated a fix thanks Moray * [https://wordpress.org/plugins/jetpack/](https://wordpress.org/plugins/jetpack/) Viewing 15 replies - 1 through 15 (of 29 total) 1 [2](https://wordpress.org/support/topic/problem-with-related-posts-3/page/2/?output_format=md) [→](https://wordpress.org/support/topic/problem-with-related-posts-3/page/2/?output_format=md) * Plugin Author [Jeremy Herve](https://wordpress.org/support/users/jeherve/) * (@jeherve) * Jetpack Mechanic 🚀 * [11 years, 1 month ago](https://wordpress.org/support/topic/problem-with-related-posts-3/#post-5963908) * Could you try the instructions mentioned here, and let me know if it helps?
