Problem with php 7.1

I am using WP 4.9.5 with the current version of advanced iframe. My host recently upgraded the PHP version on the server to pHP 7.1. Now, when I try to access my Iframe content, the wordpress page shows the following error message:

EDEPRECATED in /var/sites/c/mysitesname/publichtml/wp-content/plugins/embed-iframe/embediframe.php at line 15
Methods with the same name as their class will not be constructors in a future version of PHP; EmbedIframe has a deprecated constructor

Anybody else come across this, please, and is there a solution? My host will not agree to revert to the previous version of PHP. Many thanks to anyone kind enough to reply/help.
