The buttons I use in revslider are not displayed but the text inside them does. You will see it on the homepage. I am attaching a screenshot of what it should look like. Please do not share any screenshots of my website in public. If you must take screenshots please use the private.
I checked your site in Chrome and Firefox as well, buttons are displaying fine on my end too. Can you please share a screenshot of what you’re seeing in Chrome so we can take a closer look?
