Fatal error: Maximum execution time of 60 seconds exceeded in H:\wamp\www\custom\wp-includes\class-wp-http-curl.php

I get that answer.

I go to this file: wp-includes/deprecated.php and find this line in (deprecated) wp_get_http() function:

@set_time_limit ( 60 );

just comment out this line and it works fine.

Because wordpress hard coded that 60 seconds limit, this hard coded setting was over-ridding my php.ini settings. so I comment out that line, my php.ini settings will start working again.
