WordPress Membership Plugin
Turns out this is not an issue with the plugin at all. THe issue is with the hosting.
Thanks anyway.
Yes, I have a membership renewal page and have reused the button shortcodes from the initial subscription (join) page which work fine.
I have been through that page you mention and the site is set up exactly as per the instructions.
Could this issue I’m experiencing be due to a incorrect config in Stripe ?
Thanks
