Reply To: How to edit thankyou.php?

Hello,

Navigate to the “Appearance” section in the left-hand menu and click on “Theme Editor.”
On the right side of the Theme Editor page, you’ll see a list of files that make up your WordPresstheme. Look for the PHP file you want to edit and click on it. Note: Be cautious while editing PHP files, as incorrect modifications can break your website. It’s always a good idea to create a backup before making any changes.

Best Regards.
