Hello – I just want to ask if someone can help me with changing the color on the submit button to white/ grey. And how/where to change the “Please fill in the name field” to another language. Thank you.
You can change the color of the submit button in your theme’s stylesheet. This file can be accessed via FTP by browsing to /wp-content/themes/your-theme/style.css or by using the WordPress Admin panel > Appearance > Editor.
Something like the following CSS snippet will change the color to a light grey background.
