I have asked this question before, but it was only partly solved. So I did a clean install of Ja Rights, and only added this code to CSS:
.navbar-brand.logo-control img.logo-img {
max-height: unset !important;
}
This alllowed me to make a bigger logo, but it gets distorted in pad-view and mobile view. And the image view is to big on mobile - screens. So it is partly covered by the content of the next module - e.g. masthead or slideshow.
I have tried different sizes - the big 97x97, the smaller 64x64. Then the distortion dissapears, but the logo is still to big in mobile view.
Please, I will have to give up on this template if I this issue isn´t solved:
