Functions that have been removed in Drupal 9 or Drupal 10 are still used from this theme

Hi I fixed the error regarding to this issue but theme has a lot of work to be compatible with drupal 10.

My suggestion is open another issue to fix all this errors

The issue summary should always describe what should be fixed/changed. Neither the title nor screenshots are sufficient to describe what the issue is, even in the case a patch is provided.
In the case of a bug, the description should also list the steps necessary to reproduce the issue, starting from when the module/theme is installed.

Drupal has never had a drupal_get_patch() function.

it was used in drupal7 (https://api.drupal.org/api/drupal/includes%21common.inc/function/drupal_...)

That is drupal_get_path(), not drupal_get_patch().

Furthermore, that is not the only function that has been deprecated and then removed in a successive major release. Let's fix all those calls to functions that Drupal 10 does not implement anymore.

This is already handled in 📌 Automated Drupal 10 compatibility fixes Needs work .
