Thin blue border

Hello,

Can you please send us your website link. A border may be a outline. We need to check that.

Thanks

I tested in firefox on a windows computer and there were nothing. It happens for me on a mac, chrome.

Hello,

I am not able to find where you have added the Testimonials.

Thanks

Add following css in your theme style.css file

.testimonials-slidelist .slick-slide{outline:0;}

I like the plugin, but I also have that and I put
.testimonials-slidelist .slick-slide{outline:0;} in my style.css and it still occurs.

What else can I try to remove this?
