PHP 7.0 Compatibility

Hi!

I’ve tested all my plugins with this PHP linter:
https://ww.wp.xz.cn/plugins/php-compatibility-checker/

Unfortunately I found a problem with your plugin:

FILE: /srv/www/vhosts/nessuna.ch/httpdocs/nessuna/wp-content/plugins/spider-facebook/spider_facebook_widget.php
—————————————————————————————————————
FOUND 0 ERRORS AND 1 WARNING AFFECTING 1 LINE
—————————————————————————————————————
4 | WARNING | Use of deprecated PHP4 style class constructor is not supported since PHP 7.
—————————————————————————————————————

Would be great if you can fix this!

Regards,
Demian
