Wp booster error in all articles – update from theme version 9 to 12

Hello,

Yesterday I updated the Newspaper theme to version 12 from version 9 on my company’s website http://www.tecnaplastics.com.
It took some time to update the pages layout because some of the older blocks did not work in the recent version. Everything seems fine from the pages (homepage and other pages of the website) but when I click on a single post I get a screen that reports several errors:

wp_booster error:
td_api_base::mark_used_on_page : a component with the ID: single_template_1 is not set.
/web/htdocs/www.tecnaplastics.com/home/wp-content/plugins/td-composer/legacy/common/wp_booster/td_api.php

wp_booster error:
td_api_base::get_key : a component with the ID: single_template_1 Key: file is not set.
/web/htdocs/www.tecnaplastics.com/home/wp-content/plugins/td-composer/legacy/common/wp_booster/td_api.php

wp_booster error:
The path of the single_template_1 template not found. Did you disable a tagDiv plugin?
/web/htdocs/www.tecnaplastics.com/home/wp-content/plugins/td-composer/legacy/common/wp_booster/td_api.php

wp_booster error:
td_api_base::get_key : a component with the ID: single_template_1 Key: bg_use_featured_image_as_background is not set.
/web/htdocs/www.tecnaplastics.com/home/wp-content/plugins/td-composer/legacy/common/wp_booster/td_api.php

I also tried to add a completely new post (created with the new version of the theme already installed, while the rest of the) but I get the errors also in this case.
The site is now in “under construction mode”.
Thank you in advance,

Claudia Bosco

Dear Anamaria,
Thank you! The tagdiv standard pack plugin has fixed the problem.
Have a nice day,
