Hey there fox-didl,
How are you doing today?
This issue shouldn’t be related to our plugin or PHP 7 but rather to your server settings. The problem is most likely due to session folder not being writable (not having right permissions set on it).
You can fix this in 2 ways:
1. Contact your hosting provider and ask them to change the permissions on the session folder
2. I’ve made a mu-plugin for you that checks if session folder is writable and if it isn’t it creates another location in uploads folder where sessions are being stored. You can download it here. Once you do go to /wp-content/ and check if you have mu-plugins folder. If you do just paste that php file into the folder, if not create mu-plugins folder and paste the file there. This plugin should work out of a box .
Hope this helps and have a great day!
Cheers,
Bojan
