Now in the headlines every word starts with a capital letter. It is necessary that only the sentence begins with a capital letter or all the letters in the title are large

Hello. The design of the theme is good, but error occurs when I try to preview the headings and tags
Fatal error: Call to undefined function ecs_url() in /var/www/u0449646/data/www/mosteach.ru/wp-content/themes/corporate-education/template-parts/content.php on line 31

Hi,

I was wondering if it is possible to re-order the homepage sections of Corporate Education (free version).

Comfortable in code to make the changes if you point out the file this can be found in.

Thank you!
