 * Hi,
 * after switch from http to https I get this error in the frontend:
 * `Warning: Invalid argument supplied for foreach() in /homepages/17/d86437294/
   htdocs/_wordpress_site/wp-content/plugins/accordion-shortcode-and-widget/front/
   ac-content.php on line 63`
 * And in the backend:
    `Warning: Invalid argument supplied for foreach() in /homepages/
   17/d86437294/htdocs/_wordpress_site/wp-content/plugins/accordion-shortcode-and-
   widget/lib/admin/add-acc.php on line 21`
 * Any idea?

 * Hi,
 * there are no special chars in the domain name. I only used the “better search
   replace” plugin to replace [http://domain.xy](http://domain.xy) to [https://domain.xy](https://domain.xy)

 * This has also happened to me. I used a search and replace plugin to update everything
   in the site to https:// and now the accordion doesn’t work “invalid argument 
   supplied for foreach()..”
 * What is the solution to this problem please?
