I’ve let the plugin register new accounts when patrons connect their patreon account, but seems like the plugin doesn’t grab their emails. i had to manually add the email of each users in order for them to comment on posts, and it seems like there’s no any setting to change this.
also, i have to say that i installed the 1.1.0 version of the upcoming update, and seems like the image locking feature doesn’t work.
it just doesn’t lock any images at all. I’ve done every single step of the instructions and they’re still view able to patrons. Regardless of patreon level of contribution.
WordPress doesnt seem to be able to auto-generate rewrite rules on nginx servers. That’s what your web host uses. For that reason not only image locking, but numerous other WP plugins which create htaccess rules would have difficulty in getting to work on nginx servers unless the mod_rewrite rules from apache are translated into nginx rules and put into server (or virtual host) config manually.
Long story short, you can ask your host to put the below nginx configuration directives to your site’s config to test whether this will kickstart image protection.
You should contact whoever is hosting your WordPress website.
To comment on the other point, you would generally not want this functionality since that way you will never have up to date data about your patrons connected to your WordPress website. Not saying it’s impossible to achieve, I would however not recommend it.
