Dear Paul,
There are lots of questions in this thread, I am trying to answer them one by one.
Q1) email 'contact seller' is still not working
How do you setup the post form and email notifications?
Please follow our document to setup the form and email:
https://toolset.com/documentation/user-guides/automated-email-notifications-with-cred/
If you need assistance for it, lease provide your test site credentials in below "rivate detail box", I need to check it in a live website
Q2) With regards to the above classified website how can we add these pages
If you want to display posts created by current logged-in user, you can create a view with filter:
post's author is current logged-in user, see our document:
https://toolset.com/documentation/user-guides/filtering-views-query-by-author/#post-author-is-the-same-as-the-logged-in-user
Post author is the same as the logged in user
Q3) Or what happens if they try to place another advert using the same email address as per before - are they prompted to login
If the posts are created by visitor(non-logged-in), there will not be author in the posts, so above author filters won't be able to work, I suggest you ask the visitors to login first, then create the new AD posts.
Q4) Finally with the ‘My Account Settings’ page is this the same page as per WooCommerce uses?
No, My Account Settings are different from WooCommerce uses, as you can see it contains different functions, see screenshot: settings.JPG
You can click those sub pages, and edit them one by one, and check the codes in them, if you need assistance for it, please create new tickets for it.
Q5) How can we add the My Ads and My Messages page to the Tiltrak website and then connect these into the My Account Settings Page so they can be accessed once logged in.
What is the "Tiltrak website", if it is a wordpress website, you can create a page, and display a post view with author filters, so they will be able to see posts created by themselves.
See the document I mentioned above:
https://toolset.com/documentation/user-guides/filtering-views-query-by-author/#post-author-is-the-same-as-the-logged-in-user
You can also use Access shortcode to display different contents for logged-in user or non-logged-in visitors(guests), see our document:
