I don’t think a WP update has any way to affect a Genesis Child theme’s appearance…..unless it cleared your browser cache in the process of the update. If it did clear your cache, then that just means your logo was always at the size it’s showing now, but it’s only just now showing you the size it currently is because your cache was cleared from the update.
I did notice some customizations that were made to your CSS/stylesheet. When did you make those customizations? If they weren’t too long ago, then it could be due to the cache. That’s just my guess though.
Usually when some users make customizations to their CSS, it doesn’t show up immediately because of Browser Cache, especially if they’re using a Caching plugin. If you do a Hard Reload of the page, or switch themes, etc, the cache will be cleared and display the latest version of your stylesheet. Let me know if that makes sense.
If you can let me know how big you want your logo to appear, I can help you adjust the CSS to get it to look however you want.
Example, if you want it to show at it’s natural size (300 x 60) then we can do that by changing the .title-area width to 300px on line 1209. Then we should probably remove or adjust the background size that was added on line 1252 –
.header-image .site-title > a {
background-size: 185px 35px !important;
background-position:left center !important;
display: block;
height: 76px;
text-indent: -9999px;
}
Let me know if that helps
