Plugin activation leads to fatal error

After activating plugin the site in inacessible, I am glad I decided to first try it in local environment.

Here’s error text from Query Monitor:

Fatal error: Uncaught Error: Non-static method Warehouse_Popups_Woocommerce_Public::_wmw_get_data_from_cache() cannot be called statically
