1. Upload the file to the root directory of your site, then run http://yourdomainname/install to install, fill in the relevant information according to the prompts (be careful not to modify the database table prefix), and click "Next"... Complete the installation,
Note: If the reminder cannot be installed or the page displays dir, please enter the install folder, delete the install_lock.txt file and index.html, change the index.php.bak file to index.php, refresh the browser and re-run http:/ /your domain name/install it!
2. After installation, go to "System" - "Database Backup/Restore" on the backend, click "Restore Data" - "Start Restore Data" in the upper right corner to restore the database. (After restoring the data, if there is no data in the columns or articles, it is likely that you changed the database table prefix during installation)
3. In the backend, click "System" - "System Parameter Settings", modify the website settings, and click "OK" again. (Without this step, sometimes the front end will display the DreamWeaver default template content after the upgrade).
4. Backend, click "Generate" - "Upgrade System Cache"
5. Regenerate all pages once. OK Done.
