WP-Members Login Issue

So I’m having problems with WP Members login page. I have just installed Login Styler plugin which is great but only works on one page. So the other pages that are protected still require the normal login and register type page.

Unfortunately, when people login its just refreshing back to the same page. I’ve tried this in Explorer and everything works. I’ve cleared cache, and deleted and recreated the login and registration pages, but still no joy.

Any help or support with this would be massively appreciated.
