 * Hi, I want to upgrade to PHP7.x but WP Engine tells me there are two errors in
   your plugin (it is a great plugin by the way!) that needs to be fixed first. 
   Do you agree, can you help?
 * Name: Content Aware Sidebars
 * FILE: /xxxxxxx/wp-content/plugins/content-aware-sidebars/lib/freemius/includes/
   fs-essential-functions.php
    —————————————————————————————————————————————- FOUND
   0 ERRORS AND 1 WARNING AFFECTING 1 LINE —————————————————————————————————————————————-
   173 | WARNING | Function name “__fs” is discouraged; PHP has reserved all method
   names with a double underscore prefix for future use. —————————————————————————————————————————————-
 * FILE: /xxxxx/wp-content/plugins/content-aware-sidebars/freemius.php
    ————————————————————————————–
   FOUND 0 ERRORS AND 1 WARNING AFFECTING 1 LINE ————————————————————————————– 1

 * Sorry, I searched earlier but did not find the answer. But now I got it: [https://wordpress.org/support/topic/php-7-2-compatibility-5/](https://wordpress.org/support/topic/php-7-2-compatibility-5/)
 * So I guess solved?

 * Thanks for reporting this.
 * If you are still seing those messages, it means that it has not been solved.
   
   However, as it is only warnings, it will not mean anything for the stability 
   or security of your site.
 * Basically PHP is just complaining about a method name being prefixed with `__`,
   as that is supposed to be “reserved”.
 * You can follow the updates here: [https://github.com/Freemius/wordpress-sdk/issues/150](https://github.com/Freemius/wordpress-sdk/issues/150)
 * Does these messages mean that WP Engine refuses to upgrade your site to PHP7.
   x?

 * Thank you for answer.
    First line at the web hotel alarmed, but second line said
   it should (probably) be just fine to go ahead. So I did. And it was! We have 
   now migrated to 7.2 and it is working very well! No problem at all with content
   aware sidebars or any other plugin. Nice to finally have done the switch, and
   site is now faster.
