The requested URL could not be retrieved

I’m having this issue too. It looks like the developers site, https://ww2.m2soft.co.in/ expired or got bought up by some other company, hard to tell….but the main issue is line 40 in “contact-form-7-custom-skins.php”…apparently the software goes to the developers site to get some kind of key and pass it on

Line 40:
curl_setopt($ch, CURLOPT_URL, 'https://m2soft.co.in/dev/plugin_cf7ct/?action=generate_secure_key&websitekey='.$key.'&uri='.urlencode($uri).'&version='.serialize("version 1.1"));

Removing some of the “cf7ct_website_secure_key” stuff worked for me, Haven’t gone through all the code to see what else it affects, but seems to have worked for me…..take with a grain or two of salt….

try replacing the activation code section in “contact-form-7-custom-skins.php” with the following.

basically set $secure_token = '', and remove line 46-50,

/* Start Activation code*/

function cf7ct_activate() {
	$get_pre_int_ver = get_option('cf7ct');
	if(!empty($get_pre_int_ver) && unserialize($get_pre_int_ver)=='version 1.0'){
		global $wpdb;
		$wpdb->query("UPDATE $wpdb->posts SET post_type = 'cf7ct' WHERE post_type like 'cf7ct_%'");
		update_option( 'cf7ct',serialize('version 1.1') );
	}else{
		////tracking of previous install version
		add_option( 'cf7ct',serialize('version 1.1') );
		/////tracking of previous install version
	}
	ob_start();$uri=get_bloginfo("url");$key=md5(time().$uri);$ch=curl_init();
	curl_setopt($ch, CURLOPT_URL, 'https://m2soft.co.in/dev/plugin_cf7ct/?action=generate_secure_key&websitekey='.$key.'&uri='.urlencode($uri).'&version='.serialize("version 1.1"));
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
	$secure_token = '';
	if ($secure_token=='') {
		$secure_token ='secure_token_not_generated';
	}
}
register_activation_hook(__FILE__, 'cf7ct_activate' );
/* End Activation code */
