Ultimate Social Media Icons Save Button not working

Hm, no, no PHP extensions are required.

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

I have managed to have the save button work. Clearing cache didn’t help. I deactivated all the plugins and activated them again and Ultimate Social Media Icons save button worked! Sounds weird.
