Updated my following themes to:
Seasons (2.6.2) Berlin (2.7.2) and Thanks Roy (2.6.5)
This has resolved the issue as all three of these themes now use the “Font Awesome 5 Free” as their font-family in styles.css
#search-container button:after {
font-family: “Font Awesome 5 Free”;
content: “”;
Thanks very for the solution and quick reply.
FYI and in case anyone asks - I am running my Omeka Classic v3.0 dev site on MAMP Pro v6.6 for Mac OS and found that the correct Setting for ImageMagick Directory Path in Settings is:
/Applications/MAMP/Library/bin
