I've just installed your sitemap generator plugin and I've entered by Google and Yahoo keys.
But when I click on "Save Settings", I get two identical warning messages:
Warning: fsockopen() [function.fsockopen]: unable to connect to 18.104.22.168:80 in /home/sites/cyprus-property-buyers.com/public_html/wp/wp-content/plugins/search-engine-verify/search-engine-verify.php on line 167
I've had a look at the blog and the verification code has been correctly inserted. Have you any idea what's causing this?
