All in one seo – cant save on homepage

Dear Support team,
i have an issue with All-In-One SEO-Plugin. On my Startpage i cannot change the title,description, etc. After saving the page all the changes are lost. I tried the following fix without changing the error:

add_action(‘init’,’avia_remove_yoast_filter’);
function avia_remove_yoast_filter()
{
remove_filter(‘wpseo_pre_analysis_post_content’,’avia_wpseo_pre_analysis_post_content_fix’, 10, 1);
remove_filter(‘wpseo_video_index_content’,’avia_wpseo_video_content_fix’, 10, 2);
}
