Hi Siddharth, if you face any issues, could you please open a support thread here https://wordpress.org/support/plugin/ultimate-social-media-icons? We’re happy to provide support for free there.

Regarding your issue: Could you please clear cache? By that, I mean…

– The browser cache, see https://www.solutionbay.com/solutions/dont-know-how-to-clear-the-cache-1
– Please also check if you have a cache plugin installed. If so, please disable it temporarily, and check if it’s ok now

Does it work then?
