Thanks.
I’ve checked your logo and I’ve noticed something strange about it.
It’s an SVG file which implies that it’s suppose to be a vector-based graphic.
But upon investigation, rather than vector path/s, it had a raster based image embedded on it.
I tested the same logo on my sandbox site and it is not displaying too.
I’ve also tested a version of the logo where the SVG was half-vector / half-png and only the vector part of the logo display.
To address this, perhaps you may want to consider using a proper SVG files w/ actual vector elements rather than SVG files w/ embedded PNG in it.
Or just use a PNG image.:)
