Wordpress importer error: max execution time 60 seconds
<p>I am trying to import a Wordpress theme <a href="https://wpcom-themes.svn.automattic.com/demo/theme-unit-test-data.xml" rel="nofollow">unit test xml</a> with default <a href="https://wordpress.org/plugins/wordpress-importer/" rel="nofollow">wordpress importer</a> plugin. I get following error:  </p>

<blockquote>
  <p>Fatal error: Maximum execution time of 60 seconds exceeded in E:\XAMPP\htdocs\wp\wp-includes\wp-db.php</p>
</blockquote>

<p>This is a basic Wordpress 4.5.1 installation with no additional plugins or themes, except wordpress importer v 0.6.1, on my local XAMPP server, execution time limit is set to 6000 in php.ini and I can see this preset in xampp's php_info. 
I've already tried adding set_time_limit(6000) in wp-config.php and wp-db.php with the same ugly error as result.</p>

<p>Any ideas why is this happening and how can it be helped? </p>
