Hello all,
I am having the same problem I think. I put the simple social icons plugin into my widget menu, and the social media icons show up on MAC and mobile devices, but not Firefox or PC computers. I originally thought it was just Firefox, but it seems to be all PC’s regardless of browser. First, I see above there is a Firefox fix to put a code into a .htaccess file in the root menu for the site. I am NOT computer/tech literate at all, so I am going through the files in my file manager on the site host, but I cannot find this .htaccess file. Can anyone give me a very dumbed down step by step as to where this would be (providing it’s the same across the board)? THANKS for your time.
