I am working on a wordpress website with civiCRM. Member signup with CiviCRM is working correctly. I need an admin approve the new wordpress users after signup. I used "New User Approve" wordpress plugin for this. When the user make payment and completes the signup the page will redirect to the CiviCRM dashboard by default. But because of I am using the new user approve plugin the newly created wordpress user is not active and so that user can't sign in successfully and can't access the dashboard. That results in an error message. So I need to show a Thank you page after submitting the registration details. How can I do it?
In order to do what Joe suggests pretty certain you will need to have installed Front End Page Options extension otherwise the 'redirect' option won't exist.
Go to Contributions -> Manage Contribution Pages -> Choose ( or create ) your page -> Configure -> Thank You page Redirect
