template path file load bugfix

I think the template_path() method in QLIGG_Frontend class in frontend.php is not working properly.

You do it this way:
– check theme directory
– check plugin directory

But this way you can’t load file from the theme. Because files are always available in the plugin.
So the plugin template file always overwrites the theme template file.

So you have to change the order to function correctly:

– default check plugin directory
– check theme directory

Properly working code:

function template_path( $template_name, $template_file = false ) {

   if ( file_exists( QLIGG_PLUGIN_DIR . "templates/{$template_name}" ) ) {
      $template_file = QLIGG_PLUGIN_DIR . "templates/{$template_name}";
   }

   if ( file_exists( trailingslashit( get_stylesheet_directory() ) . "insta-gallery/{$template_name}" ) ) {
      $template_file = trailingslashit( get_stylesheet_directory() ) . "insta-gallery/{$template_name}";
   }

   return apply_filters( 'qligg_template_file', $template_file, $template_name );
}
