Site Error

Hello!

Since yesterday I have a spontaneous error message on my website. I have not changed or updated the website. But when publishing new messages, I get to see this error message above the message:

> **Warning** : Illegal string offset 'td_post_template' in **/home/vhosting/r/vhost0013083/domains/112-uitgeest.nl/htdocs/www/wordpress/wp-content/themes/Newspaper/includes/wp_booster/td_single_template_vars.php** on line **67**

The entire code of td_single_template_vars.php is:

So it has to be something with:

$ primary_category_id = td_global :: get_primary_category_id ();

but I can not figure it out. Does anyone have a solution for me?

Thanks in advance
