To understand my question, I will explain the situation first. I've installed WooCommerce PDF Invoice plugin on some subdomains and today I activated it on a new website. But when i generated the invoice ID it wont let me generate a new one.. The customer wanted to change it to something else than just starting from 1, but the plugin wont let me do it again.
So my question, is it possible somehow to reset settings for a plugin or install a plugin "from new" on a subdomain it already is installed on?
