Joe Dolson on "[Plugin: WP to Twitter] Apache2 error PHP 7"

Using Apache 2.4.18 and PHP 7.0.8-0ubuntu0.16.04.2 I get these apache errors where the rendering of the webpage leads to a bad gateway problem

[:error] [pid 9090] PHP Waing: Declaration of FDX_Widget_search::form() should be compatible with WP_Widget::form($instance) in wordpress/wp-content/plugins/wp-twitter/modules/class-p2.php on line 0

Hi! That error appears to actually be coming from a different plugin. I don't know what it is, but the files the error is citing are not located in the WP to Twitter directory and are not files used in WP to Twitter.
