Thank you for your support so far! I have a few issues that I'd like to get help with please.
1) I think the plug-in used to assign accounts the default access level of 'Visitor' to new accounts, but I can't figure how to get it do to do it now. So when someone creates an account and logs in they can't see any pages on the site as they all become blocked, however a visitor not logged in can see all the correct pages and is correctly blocked from accessing the premium pages. I'd like to avoid having to set up default visitors subscriptions if possible, I'd just like to add registered users automatically to the visitors access level. It is possible to add them manually as you can see in my screenshot below.
2) When setting the registration page 'Form Type' to "Popup registration form" would it be possible to define a max height for the popup box and have it scroll vertically? It currently overrides the page height when it opens and doesn't allow the user to scroll the page when the mouse cursor is inside the box. I've linked a screenshot below, also the formatting for the background of the box isn't quite right - though I may be able to fix this myself with some CSS but I thought you should know.
Thanks again for helping!
