Add log in and Remove color picker

Hello, I am porting over from the Joomla version of the StoreBox template and on the previous one, clicking the "My Account" button brought up a modal which allowed you to log in, or took you to the sign up page, however now it is only log in and I can't seem to find any sign up info (I may have accidentally deleted). I would also like information on how to remove the color picker.

Hello,

Color picker may be disabled in StoreBox -> template Options -> Features tab and "Style Switcher Display" option.
Regarding the "My account" link, there's no registration page included (in wordpress and the theme), so you can link to the default register form :
/wp-login.php?action=register
or create regsitration page (you can use somer 3rd party plugin).

Ok, Thank you. How can I modify the modal which pops up when you click "My Account" as a non logged in user?

Hi,
Popup may be modified in StoreBox/layout/popups.php file (lines 34-56), css is placed in StoreBox/css/stuff.css file (7.14. Log in popup section)
