How to update themes manually via FTP

Manually updating WordPress themes via FTP is feasible, provided that you are familiar with FTP operations. 1. Download and unzip the latest theme file from the official or trusted source to ensure that you get a "clean" version; 2. Use the FTP client to log in to the server, enter the /wp-content/themes/ directory to find the folder of the currently used theme; 3. Back up the original theme folder before replacing the old file to prevent problems from being restored; 4. Upload the new theme file to the corresponding directory of the server and select overwrite to keep the file structure consistent; 5. After completion, refresh the background to check the update status, and check whether the website front desk and backend page display are normal. The entire process needs to be handled with caution to avoid accidentally deleting or overwriting custom files.
