I updated my website which uses omeka to version 3.0.2 and when I did so the the majority of my icons, like the magnifying glass for the search, have just turned into these boxes.
I read somewhere that the solution might be to just update the theme. So I tried following the instructions for updating a theme and downloaded the newest version of The Daily theme and uploaded the ZIP file in the themes folder in the CPanel file manager. However, it seemed to not let me extract the files from the ZIP file and when I looked back at the actual website not only were the icons not fixed but all the text is now highlighted yellow.
Can anyone tell me how to get the icons back to normal, and if it is through updating the theme, how to do so properly?

The search engine and collapsible hamburger icons should be in the top right
