If a site was created using CodeIgniter and the url of the site changed, do I need to change anything else but the base URL in the config file? I did that but one of my links is still nor working. It requires you to click on a button, but the correct page does not load. And that started happening after we did a redirect of the old url to the new one. I hope that made sense!!! I have never used CodeIgniter before and is not even a big PHP person.
