The source V1 template shipped together needs to be added and replaced based on the destoon default template, so you must first upload an official default template and style, and then upload and replace it. 1. Upload an official default template in the space template directory (i.e. default in the template directory). Change the folder name in advance. Otherwise, if the space had this directory before, the upload will be directly replaced. The folder name and the new template are in the template directory. the folder names are consistent). 2. Transfer another copy of the official default style (i.e. default under skin, don’t forget to change the folder name to the folder name under the new template skin directory first) directory to the skin directory. 3. Select all directories in the new template and upload and replace them in the root directory of the space. Then it will be OK. 4. Change the template directory and style directory in the website background: System Maintenance -> Website Settings -> Basic Settings -> Select the new template directory for both website default style and website default template -> OK. 5. Update the template cache: System maintenance -> Template style -> Rebuild cache. 6. If the template still remains unchanged, go to System Maintenance -> Website Settings -> SEO Optimization -> Turn off the home page to generate HTML.
