Errors on font change to site

On the site, which is made on the Opencart theme, which allows you to change the font in the theme control panel. But, when I have a standard font on “Ralewey” (it is in the theme directory) I get Opencart such an error and does not change the font. Can you please tell me how to fix it and still change the font to the desired one?

This is the error that the server gives me. Errors:

If you need the code of any other files, write it.

Answer

You can simply correct the path to your scss.inc.php

Try to replace this

include_once(DIR_STORAGE . 'vendor/scss.inc.php');

with this

include_once(DIR_STORAGE . 'vendor/scssphp/scssphp/scss.inc.php');

---

Or just copy file scss.inc.php directly into /home/us392481/volkhovskiy.com/storage/vendor/
