Strange redirect or "404 Not Found" Problems?
Strong Testimonials expects to be able to use URL's like:
http://example.com/testimonial/great-service If that permalink structure is not working properly, try resetting permalinks by going to
wp-admin Settings Permalinks and simply clicking Save Changes.
This happens sometimes when another testimonials plugin is active or your theme also includes testimonials and we're all fighting over the /testimonial part of the URL.
