Hi TonbridgeSteve,
This features does not compatible with WordPress 4.3 recently, We will fix this issue in next version, sorry for that. for now you can add custom css to fix that issue:
Changing color of menu text:
.primary-navigation li a,
.primary-navigation li.current-menu-item.home a{
color:#fff /* your required color code here */
}
Changing background color of primary menu:
#pref-navbox{
background-color: #b4d6a0 !important; /* Your required color code here
}
Note: Please use the custom css plugin or child theme to write the custom css.
Thanks
no problem that it needs to be done in the css.
Thanks for your help.
