It looks like you haven't updated GK Portfolio for a bit, but an update for the latest version of Wordpress (5.5) would be amazing. I still love this theme for my portfolio site and the newest WP update messes it up for Firefox use now... (the featured images never load - they just keep spinning/loading). Still working fine on mobile and Safari. I just want to keep using this theme 
But I don't know if I can stick with it if it's going to start being bugging... it's been so great so far!
Thanks!
Matt
