Hi,
1)
This error looks to be JS related to q4 below.
2) Please add this CSS and update the color code to your required color.
.woocommerce .woocommerce-info,
.woocommerce-page .woocommerce-info {
background: #5adcff!important;
}
3)
Please use this CSS:
#logo img.retina {
width: auto!important;
}
4 Blog: I can replicate this and have reported it back to the team for updating. Edt: In the time I have written this post, the lead developer has fixed it. Update will follow shortly.
Thanks,
David.
