Hi @stuartpauljames – Thank you for your message, as well as for using our plugin.
With our plugin, we do not change or adjust anything in relation to any icons.
After checking your website, I saw that you’re loading certain files over HTTP instead of https – this is the reason while your icons are not shown either.
I suggest correcting it and giving it another try.
As a reference, here are your issues from the log (with your domain obfuscated as xxxxxxxxxxx):
