PSA about custom themes!!
The popular icon family "cappuccicons" was abandoned a while back. More recently (within the past few months), the website that hosted it vanished. Even more recently (within the past few weeks or days) that website has been taken over / replaced, and blogs that use cappuccicons are now redirecting people to shady sites with a risk of malware.
To check if your blog or pages have been affected, just go to your true desktop blog: [blogname].tumblr.com (mine is memento-morri-writes.tumblr.com). If it loads normally, you're fine! If it starts redirecting you elsewhere (aka, if you see the address in the address bar change), close the tab immediately!
Fear not!! It's an easy fix! If your blog is affected, you just need to open the code of your blog or page theme and delete this line:
As for replacing your missing icons (which would have been missing for weeks/months anyways), it's very simple, even if you have no coding experience! It essentially boils down to 1) Find a set of icons (I've used Phosphor and FontAwesome.), 2) copy the provided script into the top of your page/blog code (where you deleted the cappuccicons script from), and then 3) replacing the icon names in the code with the names of whatever icons you want from your chosen icon family.
Feel free to send me an ask or DM if you need more detailed instructions!
(Gently pinging @bebewrites / @softcodes because even though you don't use those icons, I know a lot of people follow you for coding stuff, so maybe you could give this a boost?)
