Yes that is your issue, you should be running php 7.2. Ask your hosting to install MultiPHP Manager ideally which will allow you to choose various php versions in the event of misbehaving modules.
Note: just noticed you're using version 1.7.2, possibly a lower php version is better for that, but you should be safe if hosting installs the MultiPHP so you can select any version. My guess is that your modules are going to need to be upgraded at the same time.
