Have you installed the plugin on a PHP7 site? * Thread Starter [Texiwill](https://wordpress.org/support/users/texiwill/) * (@texiwill) * [9 years, 9 months ago](https://wordpress.org/support/topic/php-70-compatibility/#post-7601510) * Hello, * Those are the errors that show up using the WPEngine “[PHP Compatibility](https://wordpress.org/plugins/php-compatibility-checker/)” plugin. While the plugin ‘may’ work in PHP 7, it would be best if there were no warnings or errors per such tools. They will be relied on when moving larger sites to PHP 7 and plugins will be dropped if they have such problems. * At the moment, I am in compatibility test mode before migrating to PHP 7. Other plugins I use are in worse shape. :} * I am more concerned about the Errors than warnings. When will PHP DROP deprecated constructors? The mixed line endings are not a huge issues. * Best regards, Edward * [mra13](https://wordpress.org/support/users/mra13/) * (@mra13) * [9 years, 9 months ago](https://wordpress.org/support/topic/php-70-compatibility/#post-7601511) * We are totally going to make sure that there is NO warning at all. Thats the only thing we will accept. * All of our plugin code (written by us) is PHP7 compatible. The only thing is that there are some features that require an external library. So if the code of that external library has issues then we have to kind of wait for that library to be updated by the respective developer. * In your particular case, the warnings are coming from a library that we use for the “Whois Info” feature. Thats not really something that you have to worry about as you probably won’t be using that feature anyway. * We will definitely be looking to upgrade that external library in our plugin as soon as we can find an updated version.
