Compatibility with PHP 7

My server will change to version 7 of PHP.

I need an update, if I do not pay an extra support to keep the old version of PHP

I used a plugin that tells me that there are compatibility bugs all over my wordpress and this is what he tells me of your plugin:

FILE: /wp-content/plugins/shortcodes-ultimate/inc/core/tools.php
————————————————————————————————————————-
FOUND 1 ERROR AFFECTING 1 LINE
————————————————————————————————————————-
681 | ERROR | Using ‘break’ outside of a loop or switch structure is invalid and will throw a fatal error since PHP 7.0
————————————————————————————————————————-
