Parse error: syntax error, unexpected 'endif' (T_ENDIF), when trying to view post-Collection of common programming errors

I have just installed a new wordpress theme and while viewing a single post I get the following error:

Parse error: syntax error, unexpected 'endif' (T_ENDIF) in
C:\xampp\htdocs\wordpress\wp-content\themes\amzola\loop-single.php on line 313

The error indicates there is an unexpected endif statement on line 313 of the file loop-single.php.

I notice on line 272 this theme’s code declares:

$orig_post = $post;
$global $post;

and later reverts the variable with:

$post = $orig_post;    

This seems incorrect, as $post will be NULL before it is globalized, therefore this logic will essentially empty the WordPress $post variable. Is it possible this action is causing a PHP error before the endif statement, throwing the above error code?

How can I easily check errors in my WordPress website?

Here is my php code of loop-single.php of a WordPress theme:

    

            

            

                

                     

                

            

            

                

                    

                

            

              

            

        

        

            

                  

                 -  )
