The principle is the same; the tools differ.
THE APPROACH
- Back up the database.
- Identify where URLs are stored: content tables, settings tables, configuration files.
- Replace http://yourdomain.com with the https form.
- Update the application's configured base URL.
- Clear caches.
JOOMLA
Update the site URL in configuration, and use an extension or a database query to replace URLs in content. Check the template settings for hardcoded logos.
DRUPAL
Update the base URL in settings, and use a search and replace module for content.
LARAVEL AND CUSTOM APPLICATIONS
Set APP_URL to the https form. Check any place URLs are constructed manually rather than from configuration.
A better long-term fix is to use relative or protocol-relative URLs in templates, so the scheme follows whatever the page was loaded with.
STATIC SITES
Edit the HTML directly, or run a find and replace across the files.
SERIALISED DATA
If the application stores serialised data, use a tool that understands it rather than a raw replace.
