This plugin is very good and handy, however it seems the major problem facing it is that, its not Compatible with Woocommerce Currency Switcher.
I have the Latest version of WordPress core, Woocommerce, Currency Switcher and the PPOM plugin installed on my site.
When a user selects products options, this plugin (PPOM) calculates and gives a different price. This can be very dangerous for a business.
When I set the “IS MULTIPLE ALLOWED” to No, it appears to work well, but that means my local customers will not be able to make payments.
The site targets local and foreign customers, so it means “IS MULTIPLE ALLOWED” cannot be set to NO.
I really hope the developer can do something about it.
Its such a great plugin, it would be a shame if I have to look for another plugin to do this efficiently.
