Well, I could guess thanks a lot

Hi Marek,

even if you changed image sizes in template options, the old cropped thumbs are used from image folder, to fix it you have to upload images again to use correct sizes. That's all.

Check BLOG again, you will see changes. I used a new images. "Problem" solved.

photos have a different aspect ratio

Hi there!

Did you mean the image doesn't cover the full space with the word 'vertical', please?

Here is the color changing custom code for you that you have indicated with a screenshot:

.sp-megamenu-parent .sp-dropdown li.sp-menu-item:after {
border-left: 7px solid red;
}

You may use your desired color in the above code.

Best Regards
