Actually, it's more a collection of errors:
1. as admin i'm receiving the email notifications, but as a user I am not. I already have the WP-Mail-SMTP plugin installed. I can't practically work my way through plugins conflicts as i have over 50 plugins, and i don't really want to switch themes to check for a theme conflict as it has a nasty habit of messing with widgets and menus. Any ideas? test form here: http://www.marrakech-riad.co.uk/testing-gravity-forms/
2. trying to click on 'preview form' prompts me to login to my wordpress install, despite being already logged in
3. the whole notifications section is displaying white text on white background for visual view, i'm having to highlight the 'hidden' text to see what is in each box... not ideal (although i can see stuff when in html view). Console in chrome was showing potential issues with the exec php plugin but even having disabled that, it's not resolved this issue.
thanks in advance for any help!
