"Undefined index" and "Array to string conversion" error with theme

I am using Katla as my current theme for my wordpress website. However I encounter a couple of errors when I use the theme,

"Notice: Undefined index: in /var/www/wptbox/wp-content/themes/blt-katla/inc/blt-functions.php on line 272 Notice: Array to string conversion in /var/www/wptbox/wp-content/themes/blt-katla/inc/blt-functions.php on line 173

Notice: Array to string conversion in /var/www/wptbox/wp-content/themes/blt-katla/inc/blt-functions.php on line 193 class="home blog logged-in admin-bar no-customize-support infinite-scroll sidebar-Array fixed-header post-layout-Array"> " This appears in the front end of the website.

I checked with the hosting server, they said that they are using PHP version 7.2. So that means the hosting is not the issue. Does anybody has any idea with the issue?
